Other Parts Discussed in Thread: PCM5100A, PCM5122
Could you please tell me what is the charge pump's frequency? I didn't fine it in the datasheet.
Thanks & Best Regards,

The charge pump can only be configured manually in the devices that have an SPI/I2C interface, such as the PCM512x/4x devices. The PCM5100A will auto-detect the LRCK/SCK ratio, and configure the clock tree to get the best case values for the charge pump.
If you take a look at table 132 of the PCM5122 datasheet, you will see examples of the clock tree values, resulting in a charge pump frequency of either 1411.2kHz or 1536kHz, depending on if the LRCK is a 44.1kHz based clock or a 48kHz based clock (respectively).
