Use FPGA to reclock audio I2S/ADAT/SPDIF signals

Hi,

As I understand your requirement, I think you are looking for clock switching. Suggest you to please go clocking architecture of whichever device that is targeted. For example, following link talks about MAX 10 clock control block.

Also check the ALTCLKCTRL IP mentioned in the same document.
