TAS5720A-Q1EVM: TAS5720A-Q1EVM

Aditya Pathak
Prodigy 10 points
Part Number: TAS5720A-Q1EVM

Tool/software:

I am trying to stream the audio from Bluetooth module through TAS5720A-Q1EVM

Not able to  interface  configurations for I2s protocol.

We have connected the below pins

          SCLK à Host MCU(CLK)

          SDIN à Host MCU(DO)

          LRCK à Host MCU(WS)

          MCLK à Not connected (but Host MCU side we have DI)

Additionally I have connected 3.3V,Ground and 12V to TI amplifier TAS5720A-Q1EVM. After this connections we have tried for audio streaming with the connected speaker, but speaker doesn’t gives the output. We have verified the speaker separately, it’s working fine.

 

Kindly support me on the below points,

  1. Pin Connections
  2. Clock frequency and Configurations
  3. Necessary input signals from Host MCU
  4. Which mode needs to maintain (Hardware/Software) and how to select this
  5. Share the protocol reference document for better understanding.
  6. Use case for SFT_CLIP( Low & High)
  7. Any other peripherals we need to use(like SPI/I2C)

Thanks in advance

    Aditya，

    Below information are all well described in datasheet. please take some time to read datasheet, and you can find where the problem is.  It would saves your time compared with ask questions here, which could back-forth check and takes many days.

    1. Pin Connections
    2. Clock frequency and Configurations
    3. Necessary input signals from Host MCU
    4. Which mode needs to maintain (Hardware/Software) and how to select this
    5. Share the protocol reference document for better understanding.
    6. Use case for SFT_CLIP( Low & High)
    7. Any other peripherals we need to use(like SPI/I2C)

    Go back to your problem directly:

    1. MCLK should be provided per datasheet description.

    2. please use oscilloscope to check the frequency of each IIS signal to make sure meet datasheet specified requirement.

    3. Please make sure pin connection (include HW/SW setting) follows datasheet application circuit.

    If there is still problem after investigated all items, we can run another round of discussion, need your help to provide below items:

    1. your schematic whihc include pin connection, and MCU 

    2. clock frequency oscilloscope capture of each input pin

    3. output waveform capture
