PCM1781: Changing SCK frequency

Hi,

Is changing SCL frequency allowed during the device is active?

If no, should we toggle Vcc?

Best Regards,

Kuramochi

    Hi Kuramochi-san,

    Changing the SCLK is acceptable by the device, but I recommend you mute the device during the transition. Abrupt changes may result in a clock error, which can produce and audible click or pop. For that reason, I suggest muting the device during the change.

    Thanks,

    Paul
