TA5704EVM 4-Channel Digital Audio Power Amplifier withHardware Control
TAS5704 customer evaluation module (EVM) demonstrates the integrated circuit (IC) TAS5704 fromTexas Instruments (TI).
TAS5704 is a 4-channel device with an I2S/RJ/LJ digital audio stream input and amplified PWM signalout. The subwoofer PWM signal is provided to an external class D power stage (TAS5601), which uses aLC demodulation filter to drive a subwoofer. For detail information about the TAS5704 device review thedevice data sheet, document number SLOS563 .
TAS5704 is designed to drive two 8- Ωloudspeakers up to 20W per channel (10%THD+N) in a BTLconfiguration. The TAS5704EVM can also be configured to drive four, 4- Ωspeakers in a single-ended(SE) configuration. Finally, the TAS5704EVM can be configured to drive 2 single-ended speakers plus 1bridge-tied speaker (2.1 mode). Review the board schematic, and TAS5601 documents for additionalinformation and more specific application information on the subwoofer daughter card and connector.
TAS5704EVM, together with other TI components on this board, is a complete 4 channel digital audioamplifier system, which includes digital input (SPDIF), analog inputs via ADC, and other features likemute, power down, output configuration control, format control, and gain control.

•Up to 26V, 3A power supply (PVCC)•5V, 500mA power supply (VIN)•Banana cables for power supplies and speakers•Optical or coaxial cable for SPDIF interface based on signal source•Two 8 Ωspeakers (BTL) or 4 Ωspeakers (SE). Resistive loads can also be used•Optional: TAS5601EVM2 (for subwoofer connection when using BTL configuration)
This chapter describes the TAS5704EVM board in regards to power supply (PSU) and system interfaces.
The TAS5704EVM module is powered using two power supply sources a 10–26V (PVCC) power supplyand a 5V (VIN) power supply. The 3.3V voltage levels are generated on the board using voltage regulatorsfrom VIN supply.
Note: The length of power supply cable must be minimized. Increasing length of PSU cable isequal to increasing the distortion for the amplifier at high output levels and low frequencies.
Maximum output stage supply voltage depends on the speaker load resistance. Check the recommendedmaximum supply voltage in the TAS5704 data sheet (SLOS563 ).

•Connect the negative node of the high voltage power supply (PGND) to the black binding post markedPGND.
There is no specific power up sequence for TAS5704, but it is recommended to power up the VINsupply first while reset is kept low for at least 1ms and then power up the PVCC.
CAUTION
Both positive and negative speaker outputs are floating and may not beconnected to ground (e.g. through an oscilloscope).
•Connect the positive (+) and negative (–) nodes of the left speaker to the corresponding metal bindingpost marked OUTA and OUTB on TAS5704EVM board.•Connect the positive (+) and negative (–) nodes of the right speaker to the corresponding metalbinding post marked OUTC and OUTD on TAS5704EVM board.•Install jumpers JP3–JP6 and JP7–JP10 for BTL configuration•The subwoofer is an option on this EVM, which is provided through connecting TAS5601EVM2 to theTAS5704EVM using connector J1. Connector J1 provides the power and corresponding PWMs to theTAS5601EVM2 (subwoofer amplifier). TAS5601EVM2 is configured in PBTL and is able to provide40W to an 8- Ωspeaker. Connect the subwoofer positive and negative nodes to the correspondingmetal binding posts on the TAS5601EVM2.
The Digital Audio Interface contains digital audio signal data (I2S). See TAS5704 Data sheet (SLOS563 )for signal timing and details not explained in this document.
RCA connector and OPTO connector are the two SPDIF interfaces. The switch S1 is used to togglebetween OPTO and RCA connector based on available signal source. Once the RCA cable or opticalcable is connected and the signal source is powered up, please verify the SPDIF lock indicator (blueLED3) to make sure there is viable signal available to the device.
The format of the DIR9001 SPDIF receiver can be changed using jumpers FMT0 and FMT1. Jumpersinstalled = 0. Jumpers removed = 1. The description of possible modes is printed on the EVM.
See the schematic of TAS5704EVM and the DIR9001 device for detail information on method by whichthe data and clocks are provided to TAS5704.

3 Jumpers and Control Utilities
3.1 Clock Frequency Change Jumper
3.2 SPDIF/PSIA Utilization Jumpers
3.3 Data Routing Jumpers
www.ti.com Jumpers and Control Utilities
In the absence of digital signal source ADC (PCM1808) may be used to convert an analog audio signal todigital signal and provide it to TAS5704. DIR9001 still provides clocks to ADC in this process. Thefrequency of the oscillator selected for DIR 9001determinse the sampling frequency in the absence ofdigital signal. If the OSC is 24MHz the sampling frequency will be set at 96kHz and if the OSC is selectedto be 12MHz the sampling frequency will be defaulted to 48kHz when there is no signal on SPDIF inputterminals. ADC is an additional feature to this board to provide flexibility in sourcing audio signal toTAS5704. Please review the datasheet of PCM1808 for detail description of the ADC on this EVM.
After connecting the loud speakers (loads), power supply, and data line, power up the VIN power supply.Then power up the PVCC power supply. It is recommended to set the PVCC level to 10 volts and thenramp it up to 20 volts to verify the cable connection functionality. It is recommended to set the gain to–3dB at start by having both GAIN ( GAIN0 and GAIN1) jumpers inserted. Note that the gain settingsmarked on the EVM are not correct. Please see Table 3 on the next page for the correct settings. Havingjumpers FM0 and FM1 inserted and FM2 removed sets the data format for the device to I2S format. Makesure the SPDIF format jumpers, FMT0 and FMT1 are removed to set the receiver format to I2S. It isimportant to note that a device RESET (S2 on the top of the board labeled MASTER RESET) needs to beapplied after each gain, format, or configuration change in order for the device to latch in the new settings.Finally, install jumpers CFG1 and CFG2 in the Config Control to select 2-CH-BTL-AD mode.
JP1: In the presence of a valid digital signal input, when SPDIF lock occurs, the user may use JP1 tochange LR clock and BIT clock. When a shunt is inserted, the SCKO = 512Fs and when the shunt isremoved the SCKO = 256Fs. Default is SCKO = 256Fs.
In the absence of a valid digital signal DIR9001 clock outputs switch to the frequency of crystal (Y1). If thecrystal is chosen to be 24MHz the LR clock will be 96KHz and if the crystal is chosen to be 12MHz the LRclock will be 48kHz.
The jumpers MCLK, LRCK, SCLK, SDATA allow the user to switch between the internal clock and datasources and external clock and data sources for instance PSIA (from AP instrument). The defaultconfiguration of these jumpers is SPDIF as it is marked on the EVM with a white arrow. PSIA outputs maybe utilized using pins 2 and 3 of the jumpers. Keep in mind that pin 3 of each jumper is connected toGND. Thus, the user must pay attention to the polarity of the PSIA output cables at the time of insertion.
Jumpers SDIN1, SDIN2: These jumpers enable the user to assign a data source to TAS5704 SDIN1 andSDIN2 pins. See Table 2 .

3.5 Data Format Jumpers
3.6 CONFIG Jumpers
Jumpers and Control Utilities www.ti.com
GAIN0 and GAIN1 jumpers enable the user to change the gain of the device. It is important to assertRESET (S2 labeled MASTER RESET) after each gain change in order for the device to recognize the newgain configuration. The truth table is shown below and also it is marked on the EVM board. However, thegain settings are WRONG on the EVM silkscreen. Refer to Table 3 for the correct gain settings.

FM0, FM1, and FM2 are used to change the data format by which TAS5704 operates. FMT0 and FMT1jumpers associated with DIR9001 in SPDIF interface enables the user to change the data format ofDIR9001 so that the data format is in sync with TAS5704 data format. Both TAS5704 and DIR9001 areset by default to operate at 24-bit I2S format. It is important to assert RESET after each format change inorder for the device to recognize the format change. The truth tables below indicate the jumperconfiguration and the data format of TAS5704 and DIR9001 (SPDIF).
