I am working on a system design that supplies 4 audio streams to an ADAU1452 from 4 different "clock" domains. Each stream will be fed into the ADAU1452 via one of it's SDATA inputs which will be working in the Raw 32-bit mode.
Because the 4 clock domains are not synchronised then each will need to go through an ASRC so my questions are:
1) Do the ASRCs work OK with 32-bit data?
2) To make the SDATA ports work in the Raw 32-bit mode it seems I should include them in my Schematic design but turn all the 'ticks' off i.e.
and use the Hardware Configuration -> Routing Matrix Tab to connect the input channels to the ASRCs
is this correct?
Thanks for any advice
