You should better have asked that in a new thread.

... and provided some information what you need in detail.

For those you intend to do AUDIO with a 50MHz OSC: There is a relation of MUL/DIV configuration of 57/14 for the PLL which can generate nearly exactly the 64 x Fs frequency = 12.288 which is the S/PDIF frequency. Some OSC tuning will help to synch to an external S/PDIF clock, such as generated by the AUDIO Codecs. I already made this real in some projects.
