Hi,

I need some detailed information about internal PLL accuracy over temperature and matching between both PLLs.

Thanks and Regards

Holger

    Hi, Holger,

    The PLL has correct results and accuracy in the operating temperature range. I only recommend to follow the next steps to have a correct matching between both PLLs.

    - Disable the I2S clocks.
    - Apply a Software Reset.
    - Write the I2C commands.
    - Enable the I2S clocks.
    - Unmute the ADCs.

    These steps will ensure that both PLLs will match and there won't be a phase misalignment.

    Best regards,
