1 Introduction
The TAS5076 is an innovative, cost-effective, high-performance 24-bit six-channel digital pulse-width
modulator (PWM) based on Equibit technology. Combined with a TI PurePath Digital audio amplifier power
stage, these devices use noise-shaping and sophisticated error-correction algorithms to achieve high power
efficiency and high-performance digital audio reproduction. The TAS5076 is designed to drive up to six digital
power devices to provide six channels of digital audio amplification. The digital power devices can be six
conventional monolithic power stages (such as the TAS5110) or six discrete dif ferential power stages using
gate drivers and MOSFETs.
The TAS5076 has six independent volume controls and mute. The device operates in AD and BD modes. This
all-digital audio system contains only two analog components in the signal chain—an LC low-pass filter at each
speaker terminal. Dynamic range of 105 dB for the front channels and 102 dB for the other channels is
achievable on the TAS5076-TAS5182 EVM using the specified ABD and interchannel delay settings. The
TAS5076 has a wide variety of serial input options including right justified (16-, 20-, or 24-bit), I2S (16-, 20-,
or 24-bit) left justified, and DSP (16-bit) data formats. The device is fully compatible with AES standard
sampling rates of 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz, including de-emphasis for
44.1-kHz and 48-kHz sample rates. The TAS5076 plus the TAS51xx power stage device combination was
designed for home theater applications such as DVD minicomponent systems, home theater in a box (HTIB),
DVD receiver, A/V receiver, or TV sets.

SLES090A—November 2003—Revised January 2004 TAS5076
2 Architecture Overview
The TAS5076 is composed of six functional elements:
•Clock, PLL, and serial data interface (I2S)
•Reset/power-down circuitry
•Serial control interface (I2C)
•Signal processing unit
•Pulse-width modulator (PWM)
•Power supply
2.1 Clock and Serial Data Interface
The TAS5076 clock and serial data interface contain an input serial data slave and the clock master/slave
interface. The serial data slave interface receives information from a digital source such as a DSP, S/PDIF
receiver, analog-to-digital converter (ADC), digital audio processor (DAP), or other serial bus master. The
serial data interface has three serial data inputs that can accept up to six channels of data at data sample rates
of 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, or 192 kHz. The serial data interfaces support left
justified and right justified for 16, 20, and 24 bits. In addition, the serial data interface supports the DSP protocol
for 16 bits and the I2S protocol for 24 bits.
The TAS5076 can function as a receiver or a generator for the MCLK_IN (master clock), SCLK (shift clock),
and LRCLK (left/right clock) signals that control the flow of data on the three serial data interfaces. The
TAS5076 is a c l o c k m a s t e r when it generates these clocks and is a clock slave when it receives these clocks.
The TAS5076 is a synchronous design that relies upon the master clock to provide a reference clock for all
of the device operations and communication via the I2C. When operating as a slave, this reference clock is
MCLK_IN. When operating as a master, the reference clock is either a TTL clock input t o X TAL_IN or a crystal
attached across XTAL_IN and XTAL_OUT.
The clock and serial data interface has two control parameters: data sample rate and clock master or slave.
2.1.1 Normal-Speed, Double-Speed, and Quad-Speed Selection
The data sample rate is selected through a terminal (DBSPD) or the serial control register 0 (0x02). The data
sample rate control sets the frequencies of the SCLK and LRCLK in clock slave mode and the output
frequencies of SCLK and LRCLK in clock master mode. There are three data rates: normal speed, double
speed, and quad speed.
Normal-speed mode supports data rates of 32 kHz, 44.1 kHz, and 48 kHz. Normal speed is supported in the
master and slave modes. Double-speed mode is used to support sampling rates of 88.2 kHz and 96 kHz.
Double speed is supported in master and slave modes. Quad-speed mode is used to support sampling rates
of 176.4 kHz and 192 kHz.
The PWM is placed in normal speed by setting the DBSPD terminal low or by setting the normal mode bits
in the system control register 0 (0x02) through the serial control interface. The PWM is placed in double speed
mode by setting the DBSPD terminal high or by setting the double speed bits in the system control register.
Quad-speed mode is supported; in slave mode it is auto-detected, and in master mode it is invoked using the
I2C serial control interface. In slave mode, if the TAS5076 is not in double speed mode, quad-speed mode
is automatically detected when MCLK_IN is 128 Fs. In master mode, the PWM is placed in quad-speed mode
by setting the quad-speed bit in the system control register through the serial control interface.
If the master clock is well behaved during the frequency transition (the high or low clock periods are not less
than 20 ns), then a simple speed selection is performed by setting the DBSPD terminal or the serial control
register.
When the sample rate is changed, the TAS5076 temporarily suspends processing, places the PWM outputs
in a hard mute (PWM P outputs low, PWM M outputs high, and all VALID signals low), resets all internal
processes, and suspends all I2C operations. The TAS5076 then performs a partial re-initialization and
noiselessly restarts the PWM output. The TAS5076 preserves all control register settings throughout this
sequence. If desired, the sample rate change can be performed while mute is active to provide a completely
silent transition. The timing of this control sequence is shown in Section 4.
Architecture Overview
8SLES090A—November 2003—Revised January 2004TAS5076
If the master clock input can encounter high clock or low clock period of less than 20 ns while the data rates
are changing, then RESET must be applied during this time. There are two recommended control procedures
for this case, depending upon whether the DBSPD terminal or the serial control interface is used. These
control sequences are shown in Section 4.
Table 2−1. Normal-Speed, Double-Speed, and Quad-Speed Operation
QUAD-SPEED CONTROL
REGISTER BIT DBSPD TERMINAL OR
CONTROL REGISTER BIT MODE SPEED SELECTION
0 0 Master or slave Normal speed
0 1 Master or slave Double speed
1 0 Master or slave Quad speed
0 0 Slave Quad speed if MCLK_IN = 128Fs
1 1 Master or slave Error
2.1.2 Clock Master/Slave Mode (M_S)
Clock master and slave mode can be invoked using the M_S (master slave) terminal.
This terminal specifies the default mode that is set immediately following a device RESET. The serial data
interface setting permits the clock generation mode to be changed during normal operation.
The transition to master mode occurs following a RESET when M_S terminal has a logic high applied.
The transition to slave mode occurs following a RESET when M_S terminal has a logic low applied.
2.1.3 Clock Master Mode
When M_S = 1 following a RESET, the TAS5076 provides the master clock, SCLK, and LRCLK to the rest of
the system. In the master mode, the TAS5076 outputs the audio system clocks MCLK_OUT, SCLK, and
LRCLK.
The TAS5076 device generates these clocks plus its internal clocks from the internal phase-locked loop (PLL).
The reference clock for the PLL can be provided by either an external clock source (attached to XTAL_IN) or
a crystal (connected across terminals XTAL_IN and XTAL_OUT). The external source attached to MCLK_IN
is 256 times (128 in quad mode) the data sample rate (Fs). The SCLK frequency is 64 times the data sample
rate and the SCLK frequency of 48 times the data sample rate is not supported in the master mode. The LRCLK
frequency is the data sample rate.

2.1.3.1 Crystal Type and Circuit
In clock master mode the TAS5076 can derive the MCLKOUT, SCLK, and LRCLK from a crystal. In this case,
the TAS5076 uses a parallel-mode fundamental crystal. This crystal is connected to the TAS5076 as shown
in Figure 2−1.

Figure 2−1. Crystal Circuit
2.1.4 Clock Slave Mode
In the slave mode (M_S = 0), the master clock, LRCLK, and SCLK are inputs to the TAS5076. The master clock
is supplied through the MCLK_IN terminal.
As in the master mode, the TAS5076 device develops its internal timing from the internal phase-locked loop
(PLL). The reference clock for the PLL is provided by the input to the MCLK_IN terminal. This input is at a
frequency of 256 times (128 in quad mode) the input data rate. The SCLK frequency is 48 or 64 times the data
sample rate. The LRCLK frequency is the data sample rate. The TAS5076 does not require any specific phase
relationship between SRCLK and MCLK_IN, but there must be synchronization. The TAS5076 monitors the
relationship between MCLK, SCLK, and LRCLK. The TAS5076 detects if any of the three clocks is absent,
if the LRCLK rate changes more than 10 MCLK cycles since the last device reset or clock error, or if the MCLK
frequency is changing substantially with respect to the PLL frequency.
When a clock error is detected, the TAS5076 performs a clock error management sequence.
The clock error management sequence temporarily suspends processing, places the PWM outputs in a hard
mute (PWM_P outputs are low, PWM_M outputs are high, and all VALID signals are low), resets all internal
processes, sets the volumes to mute, and suspends all I2C operations.
When the error condition is corrected, the TAS5076 exits the clock error sequence by performing a partial
re-initialization, noiselessly restarting the PWM output, and ramping the volume up to the level specified in
the volume control registers. This sequence is performed over a 60-ms interval. The TAS5076 preserves all
control register settings that were set prior to the clock interruption.
If a clock error occurs while the ERR_RCVRY terminal is asserted (low), the TAS5076 performs the error
management sequence up to the unmute sequence. In this case, the volume remains at full attenuation with
the PWM output at a 50% duty cycle. The volume can be restored from this latched mute state by triggering
a mute/unmute sequence by asserting and releasing MUTE either by using the terminal, the system control
register 0x01 D4, or the individual channel mute register D5−D0.

Alternatively, t h e TAS 507 6 ca n be pre vented from entering the latched mute state following a clock error when
the ERR_RCVRY terminal or the error recovery I2C command (register 0x03 bit D2) is active by writing 0x7F
to the individual error recovery register (0x04) and 0x84 to the feature enable register (0x1F).

2.1.6 DCLK
DCLK i s the internal high-frequency clock that is produced by the PLL circuitry from MCLK. The TAS5076 uses
the DCLK to control all internal operations. DCLK is 8 times the speed of MCLK in normal speed mode, 4 times
MCLK i n double speed, and 2 times MCLK in quad speed. With respect to the I2C addressable registers, DCLK
clock cycles are used to specify interchannel delay and to detect when the MCLK frequency is drifting.

2.1.7 Serial Data Interface
The TAS5076 operates as a slave only/receive only serial data interface in all modes. The TAS5076 has three
PCM serial data interfaces to accept six channels of digital data though the SDIN1, SDIN2, SDIN3 inputs. The
serial audio data is in MSB-first, twos-complement format.
The serial data interfaces of the TAS5076 can be configured in right-justified, I2S, left-justified, or DSP modes.
This interface supports 32-kHz, 44.1-kHz, 48-kHz, 88-kHz, 96-kHz, 176.4-kHz, and 192-kHz data sample
rates. The serial data interface format is specified using the data interface control register. The supported word
lengths are shown in Table 2−5.
During normal operating conditions if the serial data interface settings change state, an error recovery
sequence is initiated.

2.1.7.1 I2S Timing
I2S timing uses LRCLK to define when the data being transmitted is for the left channel or the right channel.
LRCLK i s low for the left channel and high for the right channel. A bit clock running at 48 or 64 times Fs is used
to clock in the data. There is a delay of one bit clock from the time the LRCLK signal changes state to the first
bit of data on the data lines. The data is written MSB first and is valid on the rising edge of the bit clock. The
TAS5076 masks unused trailing data bit positions. Master mode only supports a 64 times Fs bit clock.

Left-justified (LJ) timing uses LRCLK to define when the data being transmitted is for the left channel and the

or 64 times Fs is used to clock in the data. The first bit of data appears following the eighth bit-clock period
(for 24-bit data) after LRCLK toggles. In RJ mode, the last bit clock before LRCLK transitions always clocks
the LSB of data. The data is written MSB first and is valid on the rising edge of the bit clock. The TAS5076
masks unused leading data bit positions. Master mode only supports a 64 times Fs bit clock.

2.2 Reset, Power Down, and Status
The reset, power-down, and status circuitry provides the necessary controls to bring the TAS5076 to the initial
inactive condition, achieve low-power standby, and report system status.
2.2.1 Reset—RESET
The TAS5076 is placed in the reset mode by setting the RESET terminal low.
RESET is an asynchronous control signal that restores the TAS5076 to its default conditions, sets the valid
1−6 outputs low, and places the PWM in the hard mute state. Volume is immediately set to full attenuation
(there is no ramp down).
As long as the RESET terminal is held low, the device is in the reset state. During reset, all I2C and serial data
bus operations are ignored. Table 2−6 shows the device output signals while RESET is active.
Upon the release of RESET, if POWER_DWN is high, the system performs a 4-ms to 5-ms device initialization
and then ramps the volume up to 0 db using a soft volume update sequence. If MCLK_IN is not active when
RESET is released high, then a 4-ms to 5-ms initialization sequence is produced once MCLK_IN becomes
active.
During device initialization all controls are reset to their initial states. Table 2−7 shows the control settings that
are changed during initialization.
RESET must be applied during power-up initialization or while changing the master slave clock states.

Because the RESET is an asynchronous control signal, small clicks and pops can be produced during the
application (the leading edge) of this control. However, when RESET is released, the transition from the hard
mute state back to normal operation is performed synchronously using a quiet sequence.
If a completely quiet reset sequence is desired, MUTE must be applied before applying RESET.

2.2.2 Power Down—PDN
The TAS5076 can be placed into the power-down mode by holding the PDN terminal low. When the
power-down mode is entered, both the PLL and the oscillator are shut down. Volume is immediately set to full
attenuation (there is no ramp down). The valid 1−6 outputs are immediately asserted low and the PWM outputs
are placed in the hard mute state. PDN initiates device power down without clock inputs. As long as the PDN
terminal is held low, the device is in the power-down (hard mute) state.
During power down, all I2C and serial data bus operations are ignored. Table 2−8 shows the device output
signals while PDN is active.

To place the device in total power-down mode, both RESET and power-down modes must be enabled. Prior
to bringing PDN high, RESET must be brought low for a minimum of 50 ns.
Architecture Overview
17
SLES090A—November 2003—Revised January 2004 TAS5076
Because P D N is an asynchronous control signal, small clicks and pops can be produced during the application
(the leading edge) of this control. However, when PDN is released, the transition from the hard mute state back
to normal operation is performed synchronously using a quiet sequence.
If a completely quiet reset sequence is desired, MUTE must be applied before applying PDN.
2.2.3 General Status Register
The general status register is a read-only register. This register provides an indication when a volume update
is in progress or one of the channels is inactive. The device ID can be read using this register.
Volume update is in progress—Whenever a volume change is in progress due to a volume update
command or mute, this status bit is high.
Device identification code—The device identification code 0 0000 is displayed.
No internal errors (all valid signals are high)—When there are no internal errors in the TAS5076 and all
outputs are valid, this status bit is high.
One or more valid signals are inactive—If low , one or more channels of the TAS5076 are not outputting data.
The valid signals for those channels are inactive.
Inactive valid signals can be produced by one of these causes:
•One or more of the clock signals are in error.
•ERROR recover is active (low).
•The automute has silenced one or more channels that are receiving 0 inputs.
•MUTE has been set.
•Volume control has been set to full attenuation.
If this signal is high, the TAS5076 is outputting data on all channels.
2.2.4 Error Status Register
The error status register indicates historical information on control signal changes and clock errors. This
register latches these indications when they occur. The indications are cleared by writing 00h to the register.
This register is intended as a diagnostic tool to be used only when the system is not operating correctly. This
is because the error status bits are set when the data rate, serial data interface format, or master/slave mode
is changed. As a result, this register indicates an error condition even though the system is operating normally.
This register must be used only while diagnosing transient error conditions.
Any clock error or control signal terminal change that occurs since the last time the error status register was
cleared is displayed. In using this register, the first step is to initialize the device and verify that all of the clock
signals are active. Then this register must be cleared by writing 00h. After this point, the register indicates any
errors or control signal changes.
This register indicates an error condition by a high for the following conditions:
•Fs error
•A control terminal change has occurred (M_S, DBLSPD).
•LRCLK error
•MCLK_IN count error
•DCLK phase error with respect to MCLK_IN
•MCLK_IN phase error with respect to DCLK
•PWM timing error
If all bits of the register are low, no errors have occurred and no control terminals changed.
There is no one-to-one correspondence of clock error indication to a system error condition. A particular
system error can be indicated by one or more error indications in this register. The system error conditions
and the reported errors are as follows:
There is no correct number of MCLKs per LRCLK:
•Fs error has occurred.
•LRCLK error
•MCLK_IN count error

•DCLK phase error with respect to MCLK
•MCLK phase error with respect to DCLK
•PWM timing error

•SCLK error
2.3 Signal Processing
This section contains the signal processing functions that are contained in the TAS5076. The signal
processing is performed using a high-speed 24-bit signal processing architecture. The TAS5076 has the
following signal processing features:
•Individual channel soft volume with a range of 24 dB to −114 dB plus mute
•Soft mute
•Automute
•50-µs/15-µs de-emphasis filter supported in the sampling rates 32 kHz, 44.1 kHz, and 48 kHz
2.3.1 Volume Control
The gain of each output can be adjusted by a soft digital volume control for each channel. V olume adjustments
are performed using a soft gain update s-curve, which is approximated using a second-order filter fit. The curve
fit is performed over a transition interval between 41 ms and 65 ms.
The volume of each channel can be adjusted from mute to −114 dB to 24 dB in 0.5 dB steps. Because of the
numerical representation that is used to control the volume, at very low volume levels the step size increases
for gains of that are less than −96 dB. The default volume setting following power up or reset is 0 dB for all
channels. The step size adjustment is linear down to approximately −90 dB, see Figure 2−10.

The volume control format for each channel is expressed in 8 bits. The volume for each channel is set by writing
8 bits via the serial control interface. The MSB bit is written first as in the bit position 0 (LSB position).
Architecture Overview
19
SLES090A—November 2003—Revised January 2004 TAS5076
The volume for each channel can be set using a single- or multiple-address write operation to the volume
control register via the serial control interface. Changing the volume of all six channels requires that 6 registers
be updated.
To coordinate the volume adjustment of multiple channels simultaneously, the TAS5076 performs a delayed
volume update upon receiving a volume change command. Following the completion of the register volume
write operations, the TAS5076 waits for 5 ms for another volume command to be given. If no volume command
is issued in that period of time, the TAS5076 starts adjusting the volume of the channels that received volume
settings.
While a volume update is being performed, the system status register indicates that the update is in progress.
During the update, all subsequent volume control setting requests that are sent to the TAS5076 are received
and stored as a single next value for a subsequent update. If more than one volume setting request is sent,
only the last is retained.

2.3.2 Mute
The application of mute ramps the volume from any setting to the noiseless hard-mute state. There are two
methods in which the TAS5076 can be placed into mute. The TAS5076 is placed in the noiseless mute when
the MUTE terminal is asserted low for a minimum of 3 MCLK_IN cycles. Alternatively, the mute mode can be
initiated by setting the mute bit in the system control register through the serial control interface. The TAS5076
is held in mute state as long as the terminal is low or I2C mute setting is active. This command uses quiet entry
and exit sequences to and from the hard-mute state.
If an error recovery (described in the PWM section) occurs after a mute request has been received, the device
returns from error recovery with the channel volume set as specified by the mute command.
2.3.3 Automute
Automute is a n automatic sequence that can be enabled or disabled via the serial control interface. The default
for this control is enabled. When enabled, the PWM automutes an individual channel when a channel receives
from 5 ms to 50 ms of consecutive zeros. This time interval can be selectable using the automute delay
register. The default interval is 5 ms. This duration is independent of the sample rate. The automute state is
exited when two consecutive samples of nonzero data are received. The TAS5076 exit from automute is
performed quickly and preserves all music information.
This mode uses the valid low to provide a low-noise floor while maintaining a short start-up time. Noise free
entry and exit is achieved by using the PWM quiet start and stop sequences.
2.3.4 Individual Channel Mute
Individual channel mute is invoked through the serial interface. Individual channel mute permits each channel
of the TAS5076 to be individually muted and unmuted. The operation that is performed is identical to the mute
operation; however, it is performed on a per-channel basis. A TAS5076 channel is held in the mute state as
long as the serial interface mute setting for that channel is set.
2.3.5 De-Emphasis Filter
For audio sources that have been pre-emphasized, a precision 50-µs/15-µs de-emphasis filter is provided to
support the sampling rates of 32 kHz, 44.1 kHz, and 48 kHz. See Figure 2−11 for a graph showing the
de-emphasis filtering characteristics. De-emphasis is set using two bits in the system control register.

2.4 Pulse-Width Modulator (PWM)
The TAS5076 contains six channels of high performance digital Equibit PWM modulators that are designed
to drive switching output stages (back ends) in both single-ended (SE) and H-bridge (bridge tied load)
configuration. The TAS5076 device uses noise shaping and sophisticated error correction algorithms to
achieve high power efficiency and high-performance digital audio reproduction.
The PWM provides six pseudodifferential outputs to drive six monolithic power stages (such as TAS5110) or
six discrete differential power stages using gate drivers (such as the TAS5182) and MOSFETs i n single-ended
or bridged configurations. The TAS5076 also provides a high-performance dif ferential output that can be used
to drive an external analog headphone amplifier.
2.4.1 Clipping Indicator
The clipping output is designed to indicate clipping. When any of the six PWM outputs exceeds the maximum
allowable amplitude, the clipping indicator is asserted. The clipping indicator is cleared every 10 ms.
2.4.2 Error Recovery
Error recovery is used to provide error management and to permit the PWM output to be reset while preserving
all intervolume, interchannel delay, dc offsets, and the other internal settings. Error recovery is initiated by
bringing the ERR_RCVRY terminal low for a minimum 5 MCLK_IN cycles or by setting the error recovery bit
in control register 1. Error recovery is a level-sensitive signal.
The device also performs an error recovery automatically:
•When the speed configuration is changed to normal, double, or quad speed
•Following a change in the serial data bus interface configuration
When ERR_RCVRY is brought low, all valid signals go low, and the PWM_P and PWM_M outputs go low. If
there are any pending speed configurations, these changes are then performed. When ERR_RCVRY is
brought high, a delay of 4 ms to 5 ms is performed before the system starts the output re-initialization
sequence. After the initialization time, the TAS5076 begins normal operation. During error recovery, all
controls and device settings that were not updated are maintained in their current configurations.
To permit error recovery to be used to provide TAS5100 error management and recovery, the delay between
the start of (falling edge) error recovery and the falling edge of valid 1 though valid 6 is selectable. This delay
can be selected to be either 6 µs or 47 µs.
Architecture Overview

SLES090A—November 2003—Revised January 2004 TAS5076
During error recovery all serial data bus operations are ignored. At the conclusion of the sequence, the error
recovery register bit is returned to the normal operation state. Table 2−11 shows the device output signal
states during error recovery.

The transitions are done using a quiet entrance and exit sequence to prevent pops and clicks.
2.4.3 Individual Channel Error Recovery
Individual channel error recovery is used to provide error management and to permit the PWM output to be
turned off. Error recovery is initiated by setting one or more of the six error recovery bits in the error recovery
register to low.
While the error recover bits are brought low, the valid signals go to the low state. When the error recovery bits
are brought high, a delay of 4 ms to 5 ms occurs before the channels are returned to normal operation.
The delay between the falling edge of the error recover bit and the falling edge of valid 1 though valid 6 is
selectable. This delay can be selected to be either 6 µs or 47 µs.
The TAS5076 controls the relative timing of the pseudo-differential drive control signals plus the valid signal
to minimize the production of system noise during error recovery operations. The transitions to valid low and
valid high are done using an almost quiet entrance and exit sequence to prevent pops and clicks.
2.4.4 PWM DC-Offset Correction
An 8-bit value can be programmed to each of the six PWM offset correction registers to correct for any offset
present in the output stages. The offset correction is divided into 256 intervals with a total offset correction of
±1.56% of full scale. The default value is zero correction represented by 00h. These values can be changed
at any time through the serial control interface.
2.4.5 Interchannel Delay
An 8-bit value can be programmed to each of the six PWM interchannel delay registers to add a delay per
channel from 0 to 255 clock cycles. The delays correspond to cycles of the high-speed internal clock, DCLK.
Each subsequent channel has a default value that is N DCLKs larger than the preceding channel. The default
interchannel delay for the first channel and the interchannel delay between subsequent channels are mask
programmable. The present values are 0 for the first channel with increments of 53 for each successive
channel.
These values can be updated upon power up through the serial control interface. This delay is generated in
the PWM block with the appropriate control signals generated in the CTL block.
These values can be changed at any time through the serial control interface.
The optimum value for interchannel delay depends on the final system. This value can be adjusted for better
performance with regard to dynamic range and THD. It is recommended that the following TC delay values
be set instead of the default value. These TC delay values in conjunction with the ABD delay value (see
discussion in Section 2.4.6) deliver the best performance in the TAS5076-5182 EVM board.

These values must be reprogrammed every time RESET is asserted. RESET causes default values to be

2.4.6 ABD Delay
A 5-bit value is used to delay the A PWM signals with respect to B PWM signals. The value is the same for
all channels. It can be programmed from 0 to 31 DCLK clock cycles. The default ABD value is 20 DCLK clock
cycles (10100). This value is mask programmable.
This value can be changed at any time through the serial control interface.
The optimum value for ABD delay depends on the final system. This value can be adjusted for better
performance with regard to dynamic range and THD. It is recommended that the following ABD delay value
be set instead of the default value. The ABD delay value in conjunction with the TC delay values delivers the
best performance in the TAS5076−5182 EVM board.

NOTE:
The performance of a PurePath Digital amplifier system is optimized by setting the PWM
timing based upon the type of back-end device that is used and the layout. These values are
set during initialization using the I2C serial interface.
2.4.7 PWM/H-Bridge and Discrete H-Bridge Driver Interface
The TAS5076 provides six PWM outputs, which are designed to drive switching output stages (back-ends)
in both single-ended (SE) and H-bridge (bridge-tied load) configuration. The back ends can be monolithic
power stages (such as the TAS5110) or six discrete differential power stages using gate drivers (such as the
the TAS55182) and MOSFETs in single-ended or bridged configurations.
The TAS5110 device is optimized for bridge-tied load (BTL) configurations. These devices require a pure
differential PWM signal with a third signal (VALID) to control the MUTE state. In the MUTE state, the TAS5110
OUTA and OUTB are both low.

2.5 I2C Serial Control Interface
MCLK must be active for the TAS5076 to support I2C bus transactions. The TAS5076 has a bidirectional serial
control interface that is compatible with the I2C (Inter IC) bus protocol and supports both 100-kbps and
400-kbps data transfer rates for single- and multiple-byte write and read operations. This is a slave-only device
that does not support a multi-master bus environment or wait state insertion. The control interface is used to
program the registers of the device and to read device status.
The TAS5076 supports the standard-mode I2C bus operation (100 kHz maximum) and the fast I2C bus
operation (400 kHz maximum). The TAS5076 performs all I2C operations without I2C wait cycles.
The I2C bus employs two signals, SDA (data) and SCL (clock), to communicate between integrated circuits
in a system. Data is transferred on the bus serially one bit at a time. The address and data are transferred in
byte (8 bit) format with the most significant bit (MSB) transferred first. In addition, each byte transferred on the
bus is acknowledged by the receiving device with an acknowledge bit. Each transfer operation begins with
the master device driving a start condition on the bus and ends with the master device driving a stop condition
on the bus. The bus uses transitions on the data terminal (SDA) while the clock is high to indicate start and
stop conditions. A high-to-low transition on SDA indicates a start, and a low-to-high transition indicates a stop.
Normal data bit transitions must occur within the low time of the clock period. These conditions are shown in
Figure 2−13. The master generates the 7-bit slave address and the read/write (R/W) bit to open
communication with another device and then waits for an acknowledge condition. The TAS5076 holds SDA
low during acknowledge clock period to indicate an acknowledgement. When this occurs, the master transmits
the next byte of the sequence. Each device is addressed by a unique 7-bit slave address plus R/W bit (1 byte).
All compatible devices share the same signals via a bidirectional bus using a wired-AND connection. An I2C
external pullup resistor must be used for the SDA and SCL signals to set the high level for the bus.

Figure 2−13. Typical I2C Sequence
There are no limits on the number of bytes that can be transmitted between start and stop conditions. When
the last word transfers, the master generates a stop condition to release the bus. A generic data transfer
sequence is also shown in Figure 2−13.
The 7-bit address for the TAS5076 is 001101X, where X is a programmable address bit. Using the CS0
terminal on the device, the LSB address bit is programmable to permit two devices to be used in a system.
These two addresses are licensed I2C addresses and do not conflict with other licensed I2C audio devices.
To communicate with the TAS5076, the I2C master uses 0011010 if CS0 = 0 and 001101 1 if CS0 = 1. In addition
to the 7-bit device address, an 8-bit register address is used to direct communication to the proper register
location within the device interface.
Read and write operations to the TAS5076 can be done using single-byte or multiple-byte data transfers.

2.5.1 Single-Byte Write
As shown in Figure 2−14, a single-byte data write transfer begins with the master device transmitting a start
condition followed b y the I2C device address and the read/write bit. The read/write bit determines the direction
of the data transfer. For a write data transfer, the read/write bit is 0. After receiving the correct I2C device
address and the read/write bit, the TAS5076 device responds with an acknowledge bit. Next, the master
transmits the address byte or bytes corresponding to the TAS5076 internal memory address being accessed.
After receiving the address byte, the TAS5076 again responds with an acknowledge bit. Next, the master
device transmits the data byte to be written to the memory address being accessed. After receiving the data
byte, the TAS5076 again responds with an acknowledge bit. Finally, the master device transmits a stop
condition to complete the single-byte data write transfer.

A multiple-byte data write transfer is identical to a single-byte data write transfer except that multiple data bytes

the TAS5076 responds with an acknowledge bit.

2.5.3 Single-Byte Read
As shown in Figure 2−16, a single-byte data read transfer begins with the master device transmitting a start
condition followed by the I2C device address and the read/write bit. For the data read transfer, a write followed
by a read are actually done. Initially, a write is done to transfer the address byte or bytes of the internal memory
address to b e read. As a result, the read/write bit is 0. After receiving the TAS5076 address and the read/write
bit, the TAS5076 responds with an acknowledge bit. Also, after sending the internal memory address byte or
bytes, the master device transmits another start condition followed by the TAS5076 address and the read/write
bit again. This time the read/write bit is a 1 indicating a read transfer. After receiving the TAS5076 and the
read/write bit, the TAS5076 again responds with an acknowledge bit. Next, the TAS5076 transmits the data
byte from the memory address being read. After receiving the data byte, the master device transmits a not
acknowledge followed by a stop condition to complete the single-byte data read transfer.

4 System Procedures for Initialization, Changing Data Rates, and
Switching Between Master and Slave Modes
4.1 System Initialization
Reset is used during system initialization to hold the TAS5076 inactive while power (VDD), the master clock
(MCLK_IN), the device control, and the data signals become stable. The recommended initialization
sequence is to hold RESET low for 24 MCLK_IN cycles after VDD has reached 3 V and the other control
signals (MUTE, PDN, M_S, ERR_RCVRY, DBSPD, and CS0) are stable.
Figure 4−1 shows the recommended sequence and timing for the RESET terminal relative to system VDD
voltage and MCLK.

VDD

24 MCLK_IN Cycles
RESET
Figure 4−1. RESET During System Initialization
Within the first 2 ms following the low-to-high transition of the RESET terminal, the serial data interface format
must be set in the serial data interface control register using the I2C serial control interface. If the data rate
setting is other than the setting specified by the DBSPD terminal, then the data rate must be set using the
DBSPD terminal or I2C interface within 2 ms following the low-to-high transition of the RESET terminal.
The time available to set the I2C registers following the low-to-high transition of the RESET terminal can be
extended using the ERR_RCVR Y terminal. While ERR_RCVRY is low, the TAS5076 outputs are held inactive.
Once the I2C control registers are set, the ERR_RCVRY terminal can be released and the TAS5076 starts
operation. Figure 4−2 shows how the ERR_RCVRY terminal can be used to extend the interval as long as
necessary to set the I2C registers following the low-to-high transition of the RESET terminal.

The operation of the TAS5076 can be tailored as desired to meet specific operating requirements by adjusting
the following:
•Volume
•Data sample rate
•Emphasis/deemphasis settings
•Individual channel mute
•Automute delay register
•Dc-offset control registers
If desired, the TAS5076 can be set to perform an unmute sequence following the low-to-high transition of the
ERR_RCVRY terminal or the error recovery I2C command (register 0x03 bit D2). This capability is set by
writing 0x7F to the individual error recovery register (0x04) and 0x84 to the feature enable register (0x1F).
4.2 Data Sample Rate
If the master clock is well-behaved during the frequency transition (no MCLK_IN high or low clock periods less
than 20 ns), then a simple speed selection is performed by setting the DBSPD terminal or the serial control
register. If it is known at least 60 ms in advance that the sample rate is going to change, mute can be used
to provide a completely silent transition. The timing of this control sequence is shown in Figure 4−3 and
Figure 4−4.

However, if the master clock input can encounter a high clock or low clock period of less than 20 ns, then
RESET must be applied during this time. There are two recommended control procedures for this case,
depending upon whether the DBSPD terminal or the serial control interface is used. These control sequences
are shown in Figure 4−5 and Figure 4−6.
Because this sequence employs the RESET terminal the internal register settings are set to the default values.

Figure 4−5 shows the procedure to change the data rate using the DBSPD terminal and then restore the
register settings. In this example, the ERR_RCVRY terminal is used to hold off system re-initialization after
RESET is released. This permits the system controller to have as much additional time as necessary to restore
the register settings.
Once the data rate is set, the ERR_RCVRY and MUTE terminal signals are set high and the system
re-initializes.

The M_S terminal is set while the RESET terminal is active. Because this sequence employs the RESET
terminal the internal register settings are set to the default values.
Figure 4−7 shows the procedure to switch between master and slave modes and then restore the register
settings. In this example, the ERR_RCVRY terminal is used to hold off system re-initialization after RESET

register settings.
Once the data rate is set, the ERR_RCVRY and MUTE terminal signals are set high and the system
