DAC1208D750HN/C1:5 - NXP Semiconductors

1. General description

The DAC1208D750 is a high-speed 12-bit dual channel Digital-to-Analog Converter

(DAC) with selectable 2, 4 or 8 interpolating filters optimized for multi-carrier WCDMA

transmitters.

Because of its digital on-chip modulation, the DAC1208D750 allows the complex pattern

provided through lane 0, lane 1, lane 2 and lane 3, to be converted up from baseband to

IF. The mixing frequency is adjusted via a Serial Peripheral Interface (SPI) with a 32-bit

Numerically Controlled Oscillator (NCO) and the phase is controlled by a 16-bit register.

The DAC1208D750 also includes a 2 , 4 or 8 clock multiplier which provides the

appropriate internal clocks and an internal regulation to adjust the output full-scale

current.

The input data format is serial according to JESD204A specificatio n. This new interface

has numerous advantages over the traditional parallel one: easy PCB layout, lower

radiated noise, lower pin count, self-synchronous link, skew compensation. The maximum

number of lanes of the DAC1208D750 is 4 and its maximum serial data rate is

3.125 Gbps.

The Multiple Device Synchronization (MDS) guarantees a maximum skew of one output

clock period between several DAC devices. MDS incorporates modes: Master/slave and

All slave mode.

10. Application information

10.1 General description

The DAC1208D750 is a dual 12-bit DAC oper ating up to 750 Msps. With a maximum input

data rate of up to 312.5 Msps and a maximum output sampling rate of 750 Msps, the

DAC1208D750 allows more flexibility for wide bandwidth and multi-carrier systems.

Combined with its quadrature modulator and 32-bit NCO, the DAC1208D750 simplifies

the frequency selection of the system. This is also possible because of the 2, 4 or 8

interpolation filters which remove undesired images.

DAC1208D750 supports the following JESD204A key features:

•10-bit/8-bit decoding

•Code group synchronization

•inter-lane alignment

•1+x

14 +x

15 scrambling polynomial

•Character replacement

•TX/RX synchronization management via SYNC signals

•Multiple Converter Device Alignment-Multiple Lanes (MCDA-ML) device

DAC1208D750 can be interfaced wi th any logi c device that fe atures high-speed SERDES

functionality. This macro is now widely available in FPGA from different vendors.

Standalone SERDES ICs can also be used.

To enhance the intrinsic board layout simplification of the JESD204A standard, NXP

includes polarity swapping for each of the lanes and additionally offers lane swapping.

Each physical lane can be con figur ed log ically as lane0, lane1, lane2 or lane3.

NXP Semiconductors DAC1208D750

2, 4 or 8 interpolating DAC with JESD204A

This device is MCDA-ML compliant, offering inter-lane alignment between several

devices. Samples alignment be tween devices is ma int ained up to output level beca use of

an NXP proprietary mechanism. One device is configured as the master and all the ot hers

are configured as slaves. These will automatically align their output samples to the master

ones. Therefore, a system with several DAC1208D750s can produce data with a

guaranteed alignment of less than 1 DAC output clock period.

Each DAC generates two complementary current outputs on pins IOUTAP/IOUTAN and

IOUTBP/IOUTBN. This provides a full-scale output current of up to 20 mA. An int er na l

reference is available for the reference current which is externally adjustable using pin

VIRES.

The DAC1208D750 must be configured before operating. Therefore, it features an SPI

slave interface to access internal registers. Some of these registers also provide

information about the JESD204A interface status.

The DAC1208D750 requires both supplies of 3.3 V and 1.8 V. The 1.8 V supply has

separate digital and analog power supply pins. The clock input is LVDS compliant.

10.2 JESD204A receiver

The JEDEC204A defines the following parameters:

L is the number of lanes per link

M is the number of converters per device

F is the number of bytes per frame clock period

The DAC1208D750 supports both LMF = 421 and LMF = 211. The current setting is

configurabl e via th e SPI regist er s inte rf ace.

The complete Digital Layer Processing (DLP) adds a variable dela y on each lane path.

This is mainly because of the inter-lane alignment.

10.2.1 Lane input

Each lane is CML compliant. It is terminated to a common voltage with an integrated 50 

resistor.

The common-mode voltage is programmable by the SET_VCM_VOLTAGE register as

shown in Table 75 on page 55.

DC coupling is only possible if both the DAC and the transmitter have the same

common-mode voltage. If this is not the case AC coupling is required.

The deserializer performs the incoming data clock recovery and also the serial-to-parallel

conversion. Therefore, each lane includes its own PLL that must first lock.

The clock alignment module transfers the data from the regenerated clock to the frame

clock domain. The fr eq ue n cy of both clock s is the same but the phase relationship

between the clocks is unknown.

10.2.2 Sync and word align

As stated in JESD204A, the transmitter and the receiver first have to synchronize. This is

achieved through SYNC_OUT signals and a sync pattern (K28.5 symbol). The receiver

(i.e. DAC1208D750) first drives its SYNC_OUT output s. The sync pattern is continuously

sent until the receiver deasserts the SYNC_OUT signal.

The lane processing makes use of the sync patterns to synchronize the data stream,

determine the initial running disparity and extract the 10-bit word from the incoming

data stream (word-alignment).

The SYNC_OUT signal is also used during normal operation by the DAC1208D750 to

request a link reinitialization. This occurs when the 10b/8b module loses synchronization.

The SYNC_OUT signal conforms to LVDS signaling. Its common-mode voltage and its

single-ended peak amplitude can be programmed using SET_SYNC_LEVEL bits in the

SET_SYNC register s (se e Table 77 on page 55).

SYNC_OUT is asynch ro no us with the fra m e cloc k. Th e re is no timin g specification with

respect to the CLKINP and CLKINN inputs.

10.2.3 Comma detection and word align

This stag e moni tors th e da ta stream for code characters (comma detection), decodes the

words to bytes (octets) and performs optional character replace ment as part of frame/lane

alignment monitoring and corre ction. This mo dul e pr ovide s th e r equire d con trol sig nals to

the RX controller and ILA.

This module decodes the 10-bit words into 8-bit words (octets). The decoding table is

specified in the IEEE 802.3-2005 specification. During decoding, the disparity is

calculated acco rd in g to th e dis parity rules mentioned in the same specification

IEEE 802.3-2005. When the dispar ity counter is mo re than +2 or less than 2, an error will

be generated.

The following comma symbols are detected during data transmission irrespective of the

running disparity:

/K/ = K28.5

/F/ = K28.7

/A/ = K28.3

/R/ = K28.0

/Q/ = K28.4

A flag is sent to the control interface to reflect detected commas in registers.

The following flags ar e als o trig ge r ed accord in g to th e fo llowin g def initio n s:

•VALID: a code group that is found in the column of the 10b/8b decoding tables

according to the current running disparity.

•DISPARITY ERROR: The received code group exists in the 10b/8b decoding table,

but is not found in the proper column according to the current running disparity.

•NOT-IN-TABLE (NIT) ERROR: The re ce ive d cod e group is not fo un d in th e 10b /8b

decoding table for either disparity.

•INVALID: a code group that either shows a disparity error or that does not exist in the

10b/8b decoding table.

DAC1208D750 supports character replacement whatever the state of the descrambler.

When scrambling is not active, the received K28.3 /A/ or K28.7 /F/ will be replaced by the

previous sample. When scra mbling is active, the co rrespondi ng dat a octet D28.3 (0xC) or

D28.7 (0xFC) will be used.

10.2.4 Descrambler

The descrambler is a 16-bit parallel self-synchronous descrambler based on the

polynomial 1 + x14 +x

15. This processing can be turn ed off.

10.2.5 Inter-lane alignment

This feature rem ove s str ict PCB de sig n ske w com pen sa tio n be twe e n th e lanes .

10.2.5.1 Single device operation

This module handles the alignment of the four data streams. Because of inter-lane skew

and each PLL per lane concept, these alignment characters may be received at different

times by the receivers. Af ter the synchronization period, the lock signal will be HIGH. This

enables the receipt of K28.3 /A/ characters.

The /A/ characters provided in the initial alignment sequence are then used to align the

four data streams.

The ILA_CNTRL register’s SEL_ILA[1:0] bits select which K28.3 /A/ symbol triggers the

initial lane alignment:“00” = 1st /A/ symbol, “01” = 2nd /A/ symbol, “10” = 3rd /A/ symbol,

“11” = 4th /A/ symbol; Table 86 on page 61 . When all receivers have received their first

selected /A/, they st art propagating the received data to the fr ame assembly module at the

same point in time.

This module can compensate for up to 7 frame clock period misalignments between the

lanes.

When initial lane alignment is not supported, the manual alignment mode can be used.

After the initial ILA sequence, the lane alignment monitoring starts. If the received user

data contains a K28.3 /A/ symbol:

•its position is compared to the value of the alignment monitor counter

•if two successive K28.3 /A/ symbols have been received at a wrong position, a

realignment takes place

•if the buffers are empty or overflow, this is indicated by the registers

ILA_BUF_ERR_LN0 to ILA_BUF_ERR_LN3

10.2.5.2 Multi-device operation

DAC1208D750 impleme nts a multi-device inter-lane alignmen t that gua ra ntee s a ske w of

less than one output period between them.

Two modes are available: master/slave and all slave. Both make use of the MDS_P and

MDS_N pins.

Each DAC device of the system generates its own reference (ref_A in Figure 7).

If configured as a slave, an early-late comp arator compares the internal reference with the

external reference provided by the MDS pins. The comparator controls an internal buffer

that is used to delay the samples.

NXP Semiconductors DAC1208D750

2, 4 or 8 interpolating DAC with JESD204A

The MDS signal generated by the master DAC must reach all slaves within one DAC

output clock period. This induces PCB layout constraints for the MDS signal and also for

the clock distribution. Because trace lengths differ, the clock edges will reach each of the

DACs at different times.

The worst case clock skew is given by t1=PH01PH03, where PH0x represents the

sum of the trace delay and the clock skew at the output of the clock generator.

The maximum allowable trace delay for the MDS signal is given by t=TDACt1.

The worst case clock skew is given by t2=PH03PH01.

The minimum allowable trace delay for the MDS signal is given by t=t2.

In real applications, the master DAC can be anywhere and both conditions must be

satisfied: t2<tmds <TDACt1.

Example:

•clock generator skew = 80 ps

•FR4 substrate 15 cm/ns delay

•clock trace length difference = 3 cm and 4 cm

•Output sampling rate = 750 Msps

200 ps + 80 ps < tmds <1333ps(266 ps + 80 ps)

280 ps < tmds < 987 ps

10.2.5.4 All slave mode

The external refere nce is provid ed by the JESD204A tra nsmitter. All DACs are configured

in slave mode.

The MDS signal is now driven from the transmitter. It is generated at the end of the

inter-lane alignment phase (see the JESD204A standard for details).

The transmitter must also compensate for the DAC latency. Although the DAC has an

internal samples delay line, it cannot handle large delays.

In this mode, PCB layout is also important. The following delay equation applies:

t<tmds <TDACt, where t is the clock skew considered close to DAC pins.

10.2.6 Frame assembly

DAC1208D750 supports only /F/ = 1, which means that every frame clock period carries

one byte per lane. Frame assembly combines th e octet of lane_0 with the four MSB bits of

lane_1 and reassembles the original 12-bit sample. The same is done for lane_2 and

lane_3. Tail bits are dropped.

The frame assembler also handles previously triggered errors.

If scrambling is enabled:

If a nit_err (not-in-table error) or kout_unexp (unexpected control character) occurs in

lane_0 and/or lane_1, the previous 12-bit sample is repeated twice for I (lane_0,

lane_1). The same is done for Q (lane_2, lane_3).

If scrambling is disabled:

If a nit_err (not-in-table error) or kout_unexp (unexpected control character) occurs in

lane_0 and/or lane_1, the previous 12-bit sample will be repeated once for I (lane_0,

lane_1). The same is done for Q (lane_2, lane_3).

10.3 Serial Peripheral Interface (SPI)

10.3.1 Protocol description

The DAC1208D750 serial interface is a synchronous serial communication port allowing

easy interfacing with many industry microprocessors. It provides access to the registers

that define the operating modes of the chip in both Write mode and Read mode.

This interface can be configured as a 3-wire type (SDIO as bidirectional pin) or a 4-wire

type (SDIO and SDO as unidirectional pin, input and output port respectively). In both

configurations, SCLK acts as the serial clock and SCS_N acts as the serial chip select

bar.

Each read/write operation is sequenced by the SCS_N signal and enabled by a LOW

assertion to drive the chip with two bytes to five bytes, depending on the content of the

instruction byte (see Table 8).

In Table 8 below, N1 and N0 indicate the number of bytes transferred after the instruction

byte.

A[4:0] indicates which register is being addressed. In the case of a multiple transfer, this

address points to the first register to be accessed. The address is then internally

decreased after each following data phase.

R/W indicates the mode access, (see Table 7).

10.4 Clock input

The DAC1208D750 has one differential clock input, CLKINN/CLKINP.

The DAC1208D750 can ope rate with a clock frequency up to 312.5 MHz or up to 750 MHz

if the internal PLL is bypassed. The clock input can be LVDS (see Figure 15) but it can

also be interfaced with CML (see Figure 16). Error free data transition from one internal

clock domain to another one is handled by Clock Domain Interface (CDI) logic.

During the reset phase (RESET_N asserted), the clock must be stable and running. This

ensures a proper reset of the complete device.

The device has no embedded power-on-reset feature. Driving the RESET_N pin to set the

device to its default state is mandatory.

10.6 Quadrature modulator and Numerically Controlled Oscillator (NCO)

The quadrature modulator allows the 12-bit I and Q data to be mixed with the carrier

signal generated by the NCO.

The frequency of the NCO is progra mmed over 32 bit s and the sign of the sine component

can be inverted in order to operate positive or negative, lower or upper single sideband

up-conversion.

10.6.1 NCO in 32-bit

When using the NCO, the frequency can be set by the four registers FREQNCO_LSB,

FREQNCO_LISB, FREQNCO_UISB and FREQNCO_MSB over 32 bits.

The frequency for the NCO in 32-bit is calculated as follows:

(1)

where M is the decimal representation of FREQ_NCO[31:0].

The phase of the NCO can be set from 0 to 360 by both regi sters PHINCO_LSB and

PHINCO_MSB over 16 bits.

The default setting is fNCO = 96 MHz when fs = 640 Msps and the default phase is 0.

10.6.2 Low-power NCO

When using the low-power NCO, the frequency can be set by the five MSBs of register

FREQNCO_MSB.

The frequency for the low-power NCO is calculated as follows:

(2)

where M is the decimal representation of FREQ_NCO[31:27].

The phase of the low-power NCO can be set by the five MSBs of the register

PHINCO_MSB.

10.6.3 Minus_3dB

During normal use, a full-scale pattern will also be full-scale at the output of the DAC.

Nevertheless, when the I and Q dat a a re simult an eously close to full-sca le, some clipp ing

can occur and the minu s_3dB function can be used to reduce the g ain in the modulator by

3 dB. This is to keep a full-scale range at the output of the DAC without added interferers.

10.7 x / (sin x)

The roll-off effect of the DAC causes a selectable FIR filter to be inserted to compensate

for the (sin x) / x effect. This filter introduces a DC loss of 3.4 dB. The coefficients are

represented in Table 11.

10.9 Full-scale current

10.9.1 Regulation

The DAC1208D750 reference circuitry integrates an internal band gap reference voltage

which delivers a 1.29 V reference to the GAPOUT pin. It is recommended to decouple pin

GAPOUT using a 100 nF capacitor.

The reference current is generated via an external resistor of 953  (1 %) connected to

pin VIRES. A control amplifier sets th e appro pr iate full- scale curr ent (I O(fs)) for both DACs

(see Figure 17).

This configuration is optimum for temperature drif t compensation because the band gap

reference voltage can be matched to the voltage across the feedback resistor.

10.9.1.1 External regulation

The DAC current can also be set by applying an external reference voltage to the

non-inverting input pin GAPOUT and disabling the internal band gap reference voltage

with bit GAP_PD (register 00h[0]; see Table 18 “COMMON register (address 00h) bit

description”).

10.9.2 Full-scale current adjustment

The default full-scale current (IO(fs)) is 20 mA but further adjustments can be made by the

user to both DACs independently using the ser ial interface from 1.6 mA to 22 mA, 10 %.

10.11 Analog output

The DAC1208D750 has two outpu t channels e ach of which p roduces two comple ment ary

current output s. These allo w the even-order harmonics and no ise to be reduce d. The pins

are IOUTAP/IOUTAN and IOUTBP/IOUTBN respectively and need to be connected via a

load resistor RL to the 3.3 V analog power supply (VDDA(3V3)).

The equivalent analog output circuit of one DAC is shown in Figure 18. This circuit

consists of a parallel combination of NMOS current sources, and their associated

switches, for each segment.

The cascode source configuration increases the output impedance of the source, thus

improving the dynamic performance of the DAC by introducing less distortion.

The device can provide an output level (V o(p-p)) of up to 2 V, depending on the application,

the following stages and the targeted performances.

10.13 Output configuration

10.13.1 Basic output configuration

The use of a differentially-coupled transformer output provides optimum distortion

performance (see Figure 19). In addition, it helps to match the impedance and provides

electrical isolation.

The DAC1208D750 can operate at a Vo(p-p) of 2 V differential outputs. In this

configuration, it is recommended to connect the center tap of the transformer to a 62 

resistor connected to the 3.3 V analog power supply in order to adjust the DC

common-mode to approximately 2.7 V (see Figure 20).

10.13.2 DC interface to an Analog Quadrature Modulator (AQM)

When the system operation requires to keep the DC component of the spectrum, the

DAC1208D750 must use a DC interface to connect to an AQM. In this case, the offset

compensation for LO cancellation can be made with the use of the digital offset control in

the DAC.

Figure 21 is an example of a connection to an AQM with a common-mode input level

(Vi(cm)) of 1.7 V.

Figure 22 is an example of a connection to an AQM with a common-mode input level

(Vi(cm)) of 3.3 V.

The auxiliary DACs can be used to control the offset in a precise range or with precise

steps.

10.13.4 Phase correction

The Analog Quadrature Modulator which follows the DACs may have a phase imbalance

which will result in undesired sidebands. By adjusting the phase between the I and Q

channels, the spur can be reduced.

Without compensation the I and Q have a phase difference of /2 (90). The registers

PHASECORR_CNTRL0 and PHASECORR_CNTRL1 located in register page 0 allow a

phase variation from 75.7 to 104.3. The two registers define a signed value that ranges

from 512 to +511. The resulting phase compensation (in radians) is given by th e

equation: PHASE_CORR[9:0] / 2048.

10.14 Power and grounding

The power supplies should be decoupled with the following ground pins to optimize the

decoupling:

•VDDA(1V8): pin 38 with pin 37; pin 44 with pin 43 ; pin 11 with pin 12; pin 17 with pin 18;

pin 32 with pin 31

10.15 Configuration interface

10.15.1 Register description

DAC1208D750 implements indirect addressing using a p age access method. The

page-address is located at address 0x1F and is by default 0x00, which selects page 0 as

default page. For example, to access registers which configure the JESDRX, one must

first activate page 4 by writing 0x04 to the page-address 0x1F.

The DAC1208D750 contains six different pages.

The device has no embedded power-on-reset feature. Driving the RESET_N pin to set the

device to its default state is mandatory.
