Hi !

For a new design we want to implement 8xaudio in and 8xAudio Out

The used converters are from CirrusLogic DA=CS4385 and the 8ch AD(=CS5368) converter.

what is the best way for a flexible connection ? Clocking is done by an external VCXO

I think TDM mode is requested. So as mentioned in HRM two HSPORTS must be combined to archive full-duplex operation !?

 

By using 2xSports how should/could they synchronised (by connect FS-signals?? or software?)

 

A further question: TDM for CS-chips need ACLK/AFS/AD0 - when is ATDV-line required?

 

kind regards christoph
