Thanks.

    Hi, Yee Yong,

    In general, the power on/off timing for this device is quite tolerant, so we don't have any particular timing requirement for ADC/DAC power up. We recommend to follow a general sequence for power up, consisting in the following steps.

    1. Provide all the power supplies and wait for them to get stable
    2. Provide valid clocks for I²S and MCKL
    3. Remove hardware RESET condition
    4. Perform a Software RESET
    5. Configure the device
      1. Route all the channels per the required application.
      2. Turn ON the ADC and DAC
      3. Un mute ADC and DAC

    Best Regards,

    Hi Diego,

    On step 5.2, once I turned on the ADC/DAC, how long would it take to get into working state?

    Thanks.
