Hi team,

SCK does not have an external clock and only provides clock to BCK. SCK relies on internal integration for the clock signal.

Hi Gust,

The PCM510xA only support a limited number of input frequency combinations for 3-wire mode:

Assuming you are using one of those rates, it is not necessary to connect a clock signal to SCK. You should, however, connect the SCK signal to GND to use the device in 3-wire mode.

Thanks,

Paul
