TAS5766M: I2S loopback function

Part Number: TAS5766M

Hi Team,

If the TAS5766M can support the function of I2S Data Loopback for AEC?  How to set that?

If only need to set GPIO3 output selection to SDOU?  Any other  requirements of register setting and components on board? 

Thanks.

    Hi Lilian,

    The I2S output (SDOUT) from TAS5766M can be fed back to host for echo cancellation.

    What you need to do is to set the following registers to the correct values.

    a) set Page 0, Register 8 to 0x20  (GPIO3 is output)

    b) set Page 0, Register 85 (Hex 0x55) to 0x07 (SDOUT)
