Description

The CS4341A is a complete stereo digital-to-analog sys-

tem including digital interpolation, fourth-order delta-

sigma digital-to-analog conversion, digital de-emphasis,

volume control, channel mixing and analog filtering. The

advantages of this architecture include: ideal differential

linearity, no distortion mechanisms due to resistor

matching errors, no linearity drift over time and tempera-

ture and a high tolerance to clock jitter.

The CS4341A accepts data at all standard audio sample

rates up to 192 kHz, consumes very little power, oper-

ates over a wide power supply range and is pin

compatible with the CS4341, as described in section 3.1.

These features are ideal for DVD audio players.

3. APPLICATIONS

3.1 Upgrading from the CS4341 to the CS4341A

The CS4341A is pin and functionally compatible with all CS4341 designs, operating at the standard audio

sample rates, that use pin 3 as a serial clock input. In addition to the features of the CS4341, the CS4341A

supports standard sample rates up to 192 kHz, as well as automatic mode detection for sample rates be-

tween 4 and 200 kHz. The automatic speed mode detection feature allows sample rate changes between

single, double and quad-speed modes without external intervention.

The CS4341A does not support an internal serial clock mode, sample rates between 50 kHz and 84 kHz

(unless otherwise stated), or 2.7 V operation as does the CS4341.

3.2 Sample Rate Range/Operational Mode Detect

The device operates in one of three operational modes. The allowed sample rate range in each mode will

depend on whether the Auto-Detect Defeat bit is enabled/disabled.

3.2.1 Auto-Detect Enabled

The Auto-Detect feature is enabled by default in the control port register 5.1. In this state, the

CS4341A will auto-detect the correct mode when the input sample rate (Fs), defined by the LRCK

frequency, falls within one of the ranges illustrated in Table 1. Sample rates outside the specified

range for each mode are not supported.

3.2.2 Auto-Detect Disabled

The Auto-Detect feature can be defeated via the control port register 5.1. In this state, the CS4341A

will not auto-detect the correct mode based on the input sample rate (Fs). The operational mode

must be set appropriately if Fs falls within one of the ranges illustrated in Table 2. Please refer to

section 5.1.1 for implementation details. Sample rates outside the specified range for each mode

are not supported.

8DS582F2

3.3 System Clocking

The device requires external generation of the master (MCLK), left/right (LRCK) and serial (SCLK)

clocks. The LRCK, defined also as the input sample rate (Fs), must be synchronously derived from the

MCLK according to specified ratios. The specified ratios of MCLK to LRCK for each Speed Mode, along

with several standard audio sample rates and the required MCLK frequency, are illustrated in Tables 3-5.

* Requires MCLKDIV bit = 1 in the Mode Control 1 register (address 00h).

3.4 Digital Interface Format

The device will accept audio samples in several digital interface formats. The desired format is selected

via the DIF0, DIF1 and DIF2 bits in the Mode Control 2 register (see section 5.2.2) . For an illustration of

the required relationship between LRCK, SCLK and SDIN, see Figures 2-4.

3.5 De-Emphasis Control

The device includes on-chip digital de-emphasis. The Mode Control 2 bits select either the 32, 44.1, or 48

kHz de-emphasis filter. Figure 5 shows the de-emphasis curve for Fs equal to 44.1 kHz. The frequency

response of the de-emphasis curve will scale proportionally with changes in sample rate, Fs. Please see

section 5.2.3 for the desired de-emphasis control.

NOTE: De-emphasis is only available in Single-Speed Mode.

3.6 Recommended Power-up Sequence

1. Hold RST low until the power supply is stable, and the master and left/right clocks are locked to

the appropriate frequences, as discussed in section 3.3. In this state, the control port is reset to its

default settings and VQ will remain low.

2. Bring RST high. The device will remain in a low power state with VQ low.

3. Load the desired register settings while keeping the PDN bit set to 1.

4. Set the PDN bit to 0. This will initiate the power-up sequence, which lasts approximately 50 µS

when the POR bit is set to 0. If the POR bit is set to 1, see section 3.7 for a complete description

of power-up timing.

3.7 Popguard® Transient Control

The CS4341A uses Popguard® technology to minimize the effects of output transients during power-up

and power-down. This technology, when used with external DC-blocking capacitors in series with the au-

dio outputs, minimizes the audio transients commonly produced by single-ended single-supply converters.

It is activated inside the DAC when the PDN bit or the RST pin is enabled/disabled and requires no other

external control, aside from choosing the appropriate DC-blocking capacitors.

3.7.1 Power-up

When the device is initially powered-up, the audio outputs, AOUTL and AOUTR, are clamped to

AGND. Following a delay of approximately 1000 sample periods, each output begins to ramp to-

ward the quiescent voltage. Approximately 10,000 LRCK cycles later, the outputs reach VQ and

audio output begins. This gradual voltage ramping allows time for the external DC-blocking capac-

itors to charge to the quiescent voltage, minimizing the power-up transient.

3.7.2 Power-down

To prevent transients at power-down, the device must first enter its power-down state by enabling

RST or PDN. When this occurs, audio output ceases and the internal output buffers are disconnect-

ed from AOUTL and AOUTR. In their place, a soft-start current sink is substituted which allows

the DC-blocking capacitors to slowly discharge. Once this charge is dissipated, the power to the

device may be turned off and the system is ready for the next power-on.

3.7.3 Discharge Time

To prevent an audio transient at the next power-on, it is necessary to ensure that the DC-blocking

capacitors have fully discharged before turning on the power or exiting the power-down state. If

not, a transient will occur when the audio outputs are initially clamped to AGND. The time that the

device must remain in the power-down state is related to the value of the DC-blocking capacitance.

For example, with a 3.3 µF capacitor, the minimum power-down time will be approximately 0.4

seconds.

3.8 Grounding and Power Supply Arrangements

As with any high resolution converter, the CS4341A requires careful attention to power supply and

grounding arrangements if its potential performance is to be realized. Figure 1 shows the recommended

power arrangements, with VA connected to a clean supply. If the ground planes are split between digital

ground and analog ground, REF_GND & AGND should be connected to the analog ground plane.

Decoupling capacitors should be as close to the DAC as possible, with the low value ceramic capacitor

being the closest. To further minimze impedance, these capacitors should be located on the same layer as

the DAC.

All signals, especially clocks, should be kept away from the FILT+ and VQ pins in order to avoid unwant-

ed coupling into the modulators. The FILT+ and VQ decoupling capacitors, particularly the 0.1 µF, must

be positioned to minimize the electrical path from FILT+ to REF_GND (and VQ to REF_GND), and

should also be located on the same layer as the DAC. The CDB4341A evaluation board demonstrates the

optimum layout and power supply arrangements.

CS4341A

DS582F2 11

3.9 Control Port Interface

The control port is used to load all the internal register settings (see section 5). The operation of the control

port may be completely asynchronous with the audio sample rate. However, to avoid potential interference

problems, the control port pins should remain static if no operation is required.

The control port operates in one of two modes: I2C or SPI.

Notes: MCLK must be applied during all I2C communication.

3.9.1 Rise Time for Control Port Clock

When excess capacitive loading is present on the I2C clock line, pin 6 (SCL/CCLK) may not have

sufficient hysteresis to meet the standard I2C rise time specification. This prevents the use of com-

mon I2C configurations with a resistor pull-up. A workaround is achieved by placing a Schmitt

Trigger buffer, a 74HC14 for example, on the SCL line just prior to the CS4341A. This will not

affect the operation of the I2C bus as pin 6 is an input only.

3.9.2 MAP Auto Increment

The device has MAP (memory address pointer) auto increment capability enabled by the INCR bit

(also the MSB) of the MAP. If INCR is set to 0, MAP will stay constant for successive I2C writes

or reads, and SPI writes. If INCR is set to 1, MAP will auto increment after each byte is written,

allowing block reads or writes of successive registers.

Pin 6

SCL

Figure 6. I2C Buffer Example

CS4341A

12 DS582F2

3.9.3 I2C Mode

In the I2C mode, data is clocked into and out of the bi-directional serial control data line, SDA, by

the serial control port clock, SCL (see Figure 7 for the clock to data relationship). There is no CS

pin. Pin AD0 enables the user to alter the chip address (001000[AD0][R/W]) and should be tied to

VA or GND as required, before powering up the device. If the device ever detects a high to low

transition on the AD0/CS pin after power-up, SPI mode will be selected.

3.9.3a I2C Write

To write to the device, follow the procedure below while adhering to the control port

Switching Specifications in section 7.

1) Initiate a START condition to the I2C bus followed by the address byte. The upper 6 bits

must be 001000. The seventh bit must match the setting of the AD0 pin, and the eighth must

be 0. The eighth bit of the address byte is the R/W bit.

2) Wait for an acknowledge (ACK) from the part, then write to the memory address pointer,

MAP. This byte points to the register to be written.

3) Wait for an acknowledge (ACK) from the part, then write the desired data to the register

pointed to by the MAP.

4) If the INCR bit (see section 3.9.2) is set to 1, repeat the previous step until all the desired

registers are written, then initiate a STOP condition to the bus.

5) If the INCR bit is set to 0 and further I2C writes to other registers are desired, it is nec-

essary to initiate a repeated START condition and follow the procedure detailed from step

1. If no further writes to other registers are desired, initiate a STOP condition to the bus.

CS4341A

DS582F2 13

3.9.3b I2C Read

To read from the device, follow the procedure below while adhering to the control port

Switching Specifications.

1) Initiate a START condition to the I2C bus followed by the address byte. The upper 6 bits

must be 001000. The seventh bit must match the setting of the AD0 pin, and the eighth must

be 1. The eighth bit of the address byte is the R/W bit.

2) After transmitting an acknowledge (ACK), the device will then transmit the contents of

the register pointed to by the MAP. The MAP register will contain the address of the last

first operation performed on the device.

3) Once the device has transmitted the contents of the register pointed to by the MAP, issue

an ACK.

4) If the INCR bit is set to 1, the device will continue to transmit the contents of successive

registers. Continue providing a clock and issue an ACK after each byte until all the desired

registers are read, then initiate a STOP condition to the bus.

5) If the INCR bit is set to 0 and further I2C reads from other registers are desired, it is nec-

essary to initiate a repeated START condition and follow the procedure detailed from step

1. If no further reads from other registers are desired, initiate a STOP condition to the bus.

CCLK (see Figure 7 for the clock to data relationship). There is no AD0 pin. Pin CS is the chip

select signal and is used to control SPI writes to the control port. When the device detects a high to

low transition on the AD0/CS pin after power-up, SPI mode will be selected. All signals are inputs

and data is clocked in on the rising edge of CCLK.

3.9.4a SPI Write

To write to the device, follow the procedure below while adhering to the control port

Switching Specifications in section 6.

1) Bring CS low.

2) The address byte on the CDIN pin must then be 00100000.

3) Write to the memory address pointer, MAP. This byte points to the register to be written.

4) Write the desired data to the register pointed to by the MAP.

5) If the INCR bit (see section 3.9.2) is set to 1, repeat the previous step until all the desired

registers are written, then bring CS high.

6) If the INCR bit is set to 0 and further SPI writes to other registers are desired, it is nec-

essary to bring CS high, and follow the procedure detailed from step 1. If no further writes

to other registers are desired, bring CS high.

Default = 1
0 - Disabled
1 - Enabled
Function:
The Digital-to-Analog converter output will mute following the reception of  8192 consecutive audio 
samples of static 0 or  -1.  A single sample of non-zero data will release the mute. Detection and mut-
ing is done independently for each channel. The quiescent voltage on the output will be retained and 
the Mute Control pin will go active during the mute period. The muting function is affected, similiar to 
volume control changes, by the Soft and Zero Cross bits in the Transition and Mixing Control (address 
02h) register.
5.2.2  DIGITAL INTERFACE FORMAT (DIF) BIT 4-6 
Default = 000 - Format 0 (I2S, up to 24-bit data)
Function:
The required relationship between the Left/Right clock, serial clock and serial data is defined by the 
Digital Interface Format and the options are detailed in Figures 2-4. 
5.2.3  DE-EMPHASIS CONTROL ( DEM[1:0] ) BIT 2-3 
Default = 00
00 - Disabled
01 - 44.1 kHz
10 - 48 kHz

5.2.4 POPGUARD® TRANSIENT CONTROL (POR) BIT 1

Default = 1

0 - Disabled

1 - Enabled

Function:

The PopGuard® Transient Control allows the quiescent voltage to slowly ramp to and from 0 volts to

the quiescent voltage during power-on or power-down. Please refer to section 3.7 for implementation

details.

5.2.5 POWER DOWN (PDN) BIT 0

Default = 1

0 - Disabled

5.3.2 SOFT RAMP AND ZERO CROSS CONTROL (SZC) BIT 5-6

Default = 10

00 - Immediate Changes

01 - Changes On Zero Crossings

10 - Soft Ramped Changes

11 - Soft Ramped Changes On Zero Crossings

Fucntion:

Immediate Changes

When Immediate Changes is selected all level changes will take effect immediately in one step.

Changes On Zero Crossings

Changes on Zero Crossings dictates that signal level changes, either by attenuation changes or mut-

ing, will occur on a signal zero crossing to minimize audible artifacts. The requested level change will

occur after a timeout period between 512 and 1024 sample periods (10.7 ms to 21.3 ms at 48 kHz

sample rate) if the signal does not encounter a zero crossing. The zero cross function is independent-

tly monitored and implemented for each channel.

Soft Ramped Changes

Soft Ramped Changes allows level changes, both muting and attenuation, to be implemented by in-

crementally ramping, in 1/8 dB steps, from the current level to the new level at a rate of 1dB per 8

left/right clock periods.

Soft Ramped Changes on Zero Crossings

Soft Ramped Changes On Zero Crossings dictates that signal level changes, either by attenuation

changes or muting, will occur in 1/8 dB steps implemented on a signal zero crossing. The 1/8 dB level

change will occur after a timeout period between 512 and 1024 sample periods (10.7 ms to 21.3 ms

at 48 kHz sample rate) if the signal does not encounter a zero crossing. The zero cross function is

indepently monitored and implemented for each channel.

5.3.3 ATAPI CHANNEL MIXING AND MUTING (ATAPI) BIT 0-4

Default = 01001 - AOUTA = Left Channel, AOUTB = Right Channel (Stereo)

Fucntion:

The CS4341A implements the channel mixing functions of the ATAPI CD-ROM specification. Refer

to Table 7 and Figure 8 for additional information.

5.5 CHANNEL B VOLUME CONTROL (ADDRESS 04H)

5.5.1 MUTE (MUTE) BIT 7

Default = 0

0 - Disabled

1 - Enabled

Fucntion:

The Digital-to-Analog converter output will mute when enabled. The quiescent voltage on the output

will be retained. The muting function is affected, similiar to attenuation changes, by the Soft and Zero

Cross bits in the Transition and Mixing Control (address 02h) register. The MUTEC will go active dur-

ing the mute period if the Mute function is enabled for both channels.

5.5.2 VOLUME (VOLx) BIT 0-6

Default = 0 dB (No Attenuation)

Function:

The digital volume control allows the user to attenuate the signal in 1 dB increments from 0 to -90 dB.

Volume settings are decoded as shown in Table 8. The volume changes are implemented as dictated

by the Soft and Zero Cross bits in the Transition and Mixing Control (address 02h) register. All volume

settings less than - 94 dB are equivalent to enabling the Mute bit.

7. PARAMETER DEFINITIONS

Total Harmonic Distortion + Noise (THD+N)

The ratio of the rms value of the signal to the rms sum of all other spectral components over the specified

bandwidth (typically 10 Hz to 20 kHz), including distortion components. Expressed in decibels.

Dynamic Range

The ratio of the full-scale rms value of the signal to the rms sum of all other spectral components over the

specified bandwidth. Dynamic range is a signal-to-noise measurement over the specified bandwidth

made with a -60 dBFS signal. 60 dB is then added to the resulting measurement to refer the measurement

to full scale. This technique ensures that the distortion components are below the noise level and do not

affect the measurement. This measurement technique has been accepted by the Audio Engineering So-

ciety, AES17-1991, and the Electronic Industries Association of Japan, EIAJ CP-307.

Interchannel Isolation

A measure of crosstalk between the left and right channels. Measured for each channel at the converter's

output with all zeros to the input under test and a full-scale signal applied to the other channel. Units are

in decibels.

Interchannel Gain Mismatch

The gain difference between left and right channels. Units in decibels.

Gain Error

The deviation from the nominal, full-scale analog output for a full-scale digital input.

Gain Drift

The change in gain value with temperature. Units in ppm/°C.
