TAS2770: Noisy Output

Anjanaa N

Part Number: TAS2770

Hi

We are using TAS2770, which producing a noisy output (audio) even the SBCLK, FSYNC and SDIN are fine. 

How to find whether the problem is due to hardware or software?

Thanks, 

Anjanaa

    Hi, Anjanaa,

    Our team will take a look at this issue and will answer as soon as possible.

    In the meantime, could you provide details about your circuit schematic and registers configuration, please? This would be useful to get a better approach to this issue.

    Thank you.

    Best regards,

    Hi Anjanaa,

    Can you share your SBCLK and FSYNC frequencies as well as SDIN data format? (word and slot length, offset bits, etc)
    Can you share your register configuration? If you have PPC3 file it would be good as well.

    Best regards,
