PCM3168A SBAS452A–SEPTEMBER2008–REVISEDJANUARY2016 www.ti.com 9 Detailed Description 9.1 Overview The PCM3168A device is a high-performance, multi-channel codec targeted for automotive audio applications, such as external amplifiers, as well as home multi-channel audio applications (for example, home theaters and A/V receivers). The PCM3168A device consists of six-channel analog-to-digital converters (ADCs) and eight- channel digital-to-analog converters (DACs). The ADC input is selectable between single-ended and differential inputs. The DAC output type is fixed with a differential configuration. The PCM3168A device supports 24-bit linear PCM input and output data in standard audio formats (left-justified, right-justified, and I2S), DSP and TDM formats, and various sample frequencies from 8 kHz to 192 kHz (the ADC configuration supports only up to 96 kHz). The TDM format is useful to save interface bus line numbers for multi-channel audio data communication between the codec and digital audio processor. The PCM3168A device offers three modes for devicecontrol:two-wireI2Csoftware,four-wireSPIsoftware,andhardwaremodes. 9.2 Functional Block Diagram D A LRCKA BCKAD DOUT1 DOUT2 DOUT3 SCKI DIN1 DIN2 DIN3 DIN4 LRCKD BCKDA VIN1+ VOUT1+ ADC Audio Serial Interface and Clock Control DAC VIN1- VOUT1- VIN2+ VOUT2+ ADC DAC VIN2- VOUT2- VIN3+ VOUT3+ ADC DAC VIN3- VOUT3- VIN4+ VOUT4+ ADC DAC VIN4- Digital Digital VOUT4- Filter Filter and and VIN5+ VOUT5+ Volume Volume ADC DAC VIN5- VOUT5- VIN6+ VOUT6+ ADC DAC VIN6- VOUT6- VOUT7+ DAC VDD1 VOUT7- VDD2 DGND1 VOUT8+ DGND2 DAC VOUT8- VCCAD1/2 VCCDA1/2 Common and Mode Control Port AGNDAD1/2 Reference (SPI/I2C) AGNDDA1/2 VREFAD1 VREFAD2 VCOMAD VCOMDA OVF RST MODE MS/ADR0/MD0 MDO/ADR1/MD1 MDI/SDA/DEMP MC/SCL/FMT ZERO 24 SubmitDocumentationFeedback Copyright©2008–2016,TexasInstrumentsIncorporated ProductFolderLinks:PCM3168A

PCM3168A www.ti.com SBAS452A–SEPTEMBER2008–REVISEDJANUARY2016 9.3 Feature Description 9.3.1 AnalogInputs The PCM3168A device includes six ADCs, each with individual pairs of differential voltage input pins, as shown in Table 1. Additionally, the PCM3168A device has the capability of single-ended inputs. The full-scale input voltage is (0.2 × VCCAD1) V at the single-ended input mode and (0.4 × VCCAD1) V at the differential RMS RMS input mode. The input mode is selected by the MODE pin in hardware control mode or by register settings in the software control mode. In single-ended mode, VINx+ pins are used and VINx– pins must be terminated with AGNDAD1/2throughacapacitororterminatedwithVCOMAD.

Both reference pins should be connected with an analog ground via decoupling capacitors. In addition, the PCM3168A device includes two pins for common-mode voltage output (VCOMDA for DACs and VCOMAD for ADCs). These pins should be also connected with an analog ground via decoupling capacitors. Furthermore, both common pins can be used to bias external high-impedance circuits, if theyarerequired. 9.3.4 SystemClockInput The PCM3168A device requires an external system clock input applied at the SCKI input for ADC and DAC operation. The system clock operates at an integer multiple of the sampling frequency, or f . The multiples S supported in ADC operation include 256 f , 384 f , 512 f , and 768 f ; the multiples supported in DAC operation S S S S include 128 f , 192 f , 256 f , 384 f , 512 f , and 768 f .

In single rate mode, the ADC and DAC operate at an oversampling frequency of x128 (except when SCKI = 128 f and 192 f ). This mode is supported S S for sampling frequencies less than 50 kHz. In dual rate mode, the ADC and DAC operate at an oversampling frequency of x64; this mode is supported for sampling frequencies less than 100 kHz. In quad rate mode, the DAC operates at an oversampling frequency of x32. The sampling mode is automatically selected according to the ratio of system clock frequency and sampling frequency by default (for example, single rate for 512 f and S 768f ,dualratefor256f and384f ,andquadratefor128f and192f ),butmanualselectionisalsopossible S S S S S forspecifiedcombinationsthroughtheserialmodecontrolresistor.

The sequences for both reset circuits are illustrated in Figure 2, Timing Requirements: Power-On Reset, and Figure 39. Figure 2 and Timing Requirements: Power-On Reset describe the timing chart at the internal power-on reset. Initialization is triggered automatically at the point where V exceeds 2.2 V typical, and the internal reset is released after DD 3846 SCKI clock cycles from power-on if RST is kept high and SCKI is provided. VOUT from the DACs are forced to the VCOMDA level initially (0.5 × VCCDA1) and settles at a specified level according to the rising V . CC If synchronization among SCKI, BCKAD/DA, and LRCKAD/DA is maintained, VOUT starts to output with a fade- insequenceaftert fromtheinternalresetrelease;VOUTthenprovidesanoutputthatcorrespondstoDIN DACDLY1 after (3846 SCKI + t + t ) from power-on. Meanwhile, DOUT from the ADCs begins to output with a DACDLY1 DACDLY2 fade-in sequence after t from the internal reset release; DOUT then provides output corresponding to VIN ADCDLY1 after (3846 SCKI + t + t ) from power-on. If the synchronization is not held, the internal reset is not ADCDLY1 ADCDLY2 released and both operating modes are maintained at reset and power-down states; after the synchronization formsagain,boththeDACandADCreturntonormaloperationwiththeabovesequences. Figure 39 illustrates a timing chart at the external reset. RST accepts an external forced reset by RST = low, and provides a device reset and power-down state that makes the lowest power dissipation state available in the PCM3168A device. If RST goes from high to low under synchronization among SCKI, BCKAD/DA, and LRCKAD/DA, the internal reset is asserted, all registers and memory are reset, and finally the PCM3168A device enters into an all power-down state. At the same time, VOUT is immediately forced into the AGNDDA1 level and DOUT becomes 0. To begin normal operation again, toggle RST high; the same power-up sequence as power- onresetshowninFigure2isperformed.

As soon as any of the six-channel ADC digital outputs exceed the full-scale range, an overflow flag is forced high on the OVF pin. The overflow flag is held high for 1024 LRCKAD clock cycles. In parallel, overflow flag information is stored in the OVF bits of the mode control register, and the OVF bit is held until the mode control register is read. The overflow flag polarity can be changed by the OVFP bit. The OVF pin also indicates internal reset completion by transmitting a 4096 SCKIwidthpulse. 9.3.9 ZeroFlag The PCM3168A device includes a zero flag output for all DAC channels. When all of the eight-channel DACs digital inputs have continued as zero data for 1024 LRCKDA clock cycles, the zero flag is forced high on ZERO. In parallel, zero flag information is stored in the ZERO bits according to channel. The zero flag polarity can be changed by the ZREV bit. Also, the zero flag function can be selected by the AZRO bits. AND or OR logic for stereo,sixchannels,andeightchannelscanbeselected. 9.3.10 Four-Wire(SPI)SerialControl The PCM3168A device includes an SPI-compatible serial port that operates asynchronously with the audio serial interface. The control interface consists of MDI/SDA/DEMP, MDO/ADR1/MD1, MC/SCL/FMT, and MS/ADR0/MD0. MDI is the serial data input to program the mode control registers. MDO is the serial data output to read back register settings and some flags. MDO is inactive (Hi-Z, high impedance) during MS = high.

Therefore, SCKI and LRCKAD/DA must have a specific relationship in slave mode. The PCM3168A device does not need a specific phase relationship between the audio interface clocks (LRCKAD/DA, BCKAD/DA) and the system clock (SCKI), but does require a specific frequency relationship (ratiometric) between LRCKAD/DA, BCKAD/DA,andSCKI. If the relationship between SCKI and LRCKDA changes more than ±2 BCKDA clocks because of jitter, sampling frequencychange,andsoforth,theDACinternaloperationhaltswithin1/f ,andtheanalogoutputisforcedinto S VCOMDA (0.5 VCCDA1) until re-synchronization between SCKI, LRCKDA, and BCKDA is completed and then t passes. If the relationship between SCKI and LRCKAD changes more than ±2 BCKADs because of DACDLY3 jitter, sampling frequency change, and so forth, the ADC internal operation halts within 1 / f , and the digital S output is forced into a 0 code until re-synchronization between SCKI, LRCKAD, and BCKAD is completed and then t passes. In the event the change is less than ±2 BCKAD/DAs, re-synchronization does not occur, ADCDLY3 andthisanalog/digitaloutputcontrolanddiscontinuitydonotoccur. Figure 7 shows the DAC analog output and ADC digital output for loss of synchronization. During undefined data periods, some noise may be generated in the audio signal. Also, the transition of normal to undefined data and undefined (or zero) data to normal data creates a discontinuity of data on the analog and digital outputs, which thenmaygeneratesomenoiseintheaudiosignal. Both ADC outputs (DOUTx) and DAC outputs (VOUTx) hold the previous state if the system clock halts, but the asynchronous and re-synchronization processes would occur after the system clock resumes.

Table31.DesignParameters DESIGNPARAMETER EXAMPLEVALUE PCMaudio,differentialanalog Audioinput audio PCMaudio,differentialanalog Audiooutput audio Control I2C,SPI 10.2.2 DetailedDesignProcedure 10.2.2.1 AnalogInputandOutput It is recommended that input and output filters be used to condition the inputs and outputs. Input filters can be used to convert a single ended signal into a differential signal while also attenuating out of band noise. Another use of an input filter for the ADC it to reduce a 2-V signal to a 1-V input, which is the limit of the ADC RMS RMS input.

PCM3168A www.ti.com SBAS452A–SEPTEMBER2008–REVISEDJANUARY2016 12 Layout 12.1 Layout Guidelines 12.1.1 Power-SupplyPins(VCCAD1/2,VCCDA1/2,andVDD1/2) The digital and analog power-supply pins of the PCM3168A device should be bypassed to the corresponding ground pins with 1-μF ceramic capacitors placed as close to the pins as possible. Each power-supply line (V CC and V ) to the PCM3168A device should be bypassed to the corresponding ground pins with 10-μF electrolytic DD capacitorstomaximizethedynamicperformanceoftheADCandDAC. Although the PCM3168A device has two power lines to maximize the potential of dynamic performance, using one common source (for instance, a 5-V power supply for V and a 3.3-V power supply for V generated from CC DD one common source) is recommended to avoid unexpected power-supply trouble such as latch-up or incorrect power-supply conditions. Also, simultaneous power-on/off of V and V is recommended to avoid unexpected CC DD transient responses in outputs, though the power-supply sequence of V and V is not specified in the CC DD operationandabsolutemaximumratingspointofview. 12.1.2 Grounding(AGNDAD1/2,AGNDDA1/2,andDGND1/2) To maximize the dynamic performance of the PCM3168A device, the analog and digital grounds are not connected internally. These pins should have very low impedances to avoid digital noise and signal components feeding back into the analog ground. All ground pins should be connected directly to each other under the part, and the device should be connected to the analog ground of the application, as with acceptable analog layout practices;thislayoutreducesthepotentialofnoiseproblems. 12.1.3 VIN1±,VIN2±,VIN3±,VIN4±,VIN5±,andVIN6± Pins In case of direct interface to VINx±, 1-μF electrolytic capacitors are recommended because the ac-coupling capacitor (which gives a 2-Hz HPF corner frequency and 47-Ω and 0.1-μF to 470-Ω and 0.001-μF differential LPF) is recommended as the anti-aliasing filter that gives a 160-kHz LPF corner frequency. If signal source impedance is not enough (too low) or input line length to the VINx± is not enough (too short), insertion of an analogfront-endbuffer(seeFigure58toFigure60)isrecommendedtomaximizethedynamicperformance.The voltage coefficient of the capacitor for an anti-aliasing filter should be considered to maximize the THD performance. A film-type capacitor is recommended; if a ceramic capacitor is used, a relatively higher voltage typeisrecommended. There are three ways to terminate any unused input pins. First, terminate these pins to AGNDAD with 0.001-μF to 1-μF capacitors. This termination is applied on unused pins whose channels are configured in single-ended mode. The second form of termination is to connect the positive (+) pin and negative (–) pins together and terminatingthesetoAGNDADwith0.001-μFto1-μFcapacitors.Thisoptionappliestounusedpinswithchannels that are configured in differential mode. The last termination method is to terminate the pins directly to VCOMAD; this option can be applied on unused pins with unused channels combined into two channels that are then configuredinpower-savemode. 12.1.4 VCOMADandVCOMDAPins 10-μF electrolytic capacitors are recommended between VCOMAD and AGNDAD, and VCOMDA and AGNDDA to ensure a low source impedance of ADC and DAC common voltages. These capacitors should be located as closetoeachpinaspossibletoreducedynamicerrorsontheADCandDACcommonvoltages. 12.1.5 VREFAD1/2Pins 10-μF electrolytic capacitors are recommended between VREFAD1/2 and AGNDAD to ensure low source impedances of ADC references. These capacitors should be located as close to each pin as possible to reduce dynamicerrorsonADCreferences.

PCM3168A SBAS452A–SEPTEMBER2008–REVISEDJANUARY2016 www.ti.com Layout Guidelines (continued) 12.1.6 VOUT1±,VOU2±,VOUT3±,VOUT4±,VOUT5±,VOUT6±,VOUT7±,andVOUT8± Pins The differential to single-ended buffer with post LPF can be directly connected (without capacitors) to these output pins (see Figure 62), thereby minimizing the use of coupling capacitors for the 2-V outputs. The op RMS amp and resistors must be determined with consideration of degrading some performance through this differential to single-ended and LPF buffer; there is about 1.5-dB degradation seen in the examples of Figure 61 andFigure62. 12.1.7 MODEPin This pin is a logic input with quad-state input capability. The MODE pin is high when connected to V , low when DD connected to DGND, and pulled up or pulled down through an external resistor and for the two mid-states in order to distinguish the four input states. The pull-up or pull-down resistor must be 220 kΩ, ±5% in tolerance. NotethatthestateoftheMODEpinisonlysampledbyapower-onoralow-to-hightransitionoftheRSTpin. 12.1.8 RSTPin When the MODE pin setting changes to change the operating mode, the new mode setting does not take effect immediately; a RST pin toggle is required to make the new mode setting valid, and for the new mode to take effect. 12.1.9 OVFPin The OVF pin has two functions. It is primarily the flag for ADC overflow occurrence detection. It is also used to indicatethattheinternalresetsequenceiscompleteandthatthedeviceisreadytoenterserialmodecontrol. 12.1.10 SystemClockandAudioInterfaceClocks The quality of SCKI may influence dynamic performance, because the PCM3168A device (both the ADC and DAC) operates based on SCKI. Therefore, it may be required to consider the jitter, duty, and rise and fall time of thesystemclock. In slave mode, the PCM3168A device does not require a specific timing relationship between BCKAD/LRCKAD and SCKI, and BCKDA/LRCKDA and SCKI; however, there is a possibility of performance degradation with a certain timing relationship between them. In that case, specific timing relationship control might resolve this performancedegradation. In master mode, there is a possibility of performance degradation because of heavy loads on BCKAD/LRCKAD, BCKDA/LRCKDA, and DOUT1/2/3. It is recommended to load these pins as lightly as possible. Note that all outputclocksandsignalsgolow;theydonotgointoahigh-impedancestateduringpower-savemode. 12.1.11 PowerPAD The PowerPAD of the PCM3168A device is internally connected to the substrate of the silicon. It should be connected to the ground plane with sufficient low conductance in electrical and thermal; see Figure 54. The PowerPADsizeis7.25mmx7.00mm(0.725cm ×0.7cm). 12.1.12 ExternalMuteControl For power-down ON/OFF control without the pop-noise that is generated by a DC level change on the DAC output, the external mute control is generally required. Use of the following control sequence is recommended: external mute ON, codec power-down ON, SCKI stop and resume if necessary, codec power-down OFF, and externalmuteOFFcontrol. 56 SubmitDocumentationFeedback Copyright©2008–2016,TexasInstrumentsIncorporated ProductFolderLinks:PCM3168A
