TAS2770: SDOUT config

Harikrishna MG
Prodigy 10 points
Part Number: TAS2770


Tool/software:

I’m configuring the SDOUT pin on the TAS2770 to transmit feedback data, but I’m not seeing any output. The SDIN is connected to an audio processor (XMOS), and it's working fine. I probed the SDOUT pin during playback but didn’t see any data coming from pin. Can anyone help with the register settings required to enable SDOUT for output?
we require audio feedback to be fed to the Audio codec

    Hey Harikrishna, 

    TAS2770 SDOUT pin doesn't show anywhere it provides an audio loopback feature. 

    This is a list of data the SDOUT pin provides in TDM mode. 

    You can find more info from the DS in sections 8.4.1 to 8.4.2 describing the SDOUT TDM port features. 

    Regards,

    Ore.
