Hi,
My TAS3251EVM is not working. The configuration I set for the TAS3251EVM is as below:
- TAS3251EVM as slave device (I2S)
- The I2S master is from my prototype board - providing the BCLK, SDIN and LRCK to the TAS3251EVM
- R54 and R55 is removed (I2C from MSP430), supplying I2C from my prototype board.
- J37 - OUT (AIB I2S)
- J35 - Slave enable
- PLL is enabled.
- R168 is removed, and /I2S-BUF-EN is forced to be low (connect to GND).
At the test pin between the heat sink and J9, I can see that the data of BCLK, LRCLK and SDIN are correct.
I can see that a 600kHz switching waveform was output from the SPK_OUT pin (but no sound).
