Reclocking (implementation)

(mail to Guido Tent)

Hello,

I am considering buying an XO-DAC, but I have one technical question before purchasing.
I have use CS8414 and AD1865N (Audio Note config).

Using XO-DAC will get MCK (and DGND) from the CS8414 and will output clean clock. Since no filter is being used, connection is not so straight forward.
CS8414 has outputs:
- MCK
- this is being replaced by XO-DAC
- SCK (=MCK/4)
- I can get this by dividing new MCK (2 flip-flops)

The question is what to do with these:

- FSYNC
- SDATA

I guess simply aligning them (w/ D flip-flops) to the new MCK, is the best ting to do? Right.
Well, decoding SDATA and FSYNC to left/right data before D flip-flops is slightly better - to avoid gate's jitter.
