Other Parts Discussed in Thread: PCM1862

Hi Sir
I want to setting master mode on PCM1862. The external crystal is 24.576MHz.

How do we need to modify 0x20 or other registers？

Thanks for your support.

    Hi Hugo,

    If you are using a 24.576 MHz crystal as the SCK then you will only need to adjust the dividers for LRCK and BCK output. This can be done in register 0x27 and 0x26. Keep in mind that the BCK to LRCK ratio should be 64 unless you are in TDM mode. Please look at "Figure 29. PCM186x Main Audio Clock Tree and Clock Generation" in the data sheet for more information.
