spdif Input

Hello,

We are developing a high end Audio DA/AD board with the ADSP-SC589. For this we need S/PDIF Input with a rate of 192K/24bit.

We are now testing the prototypes and we face problems on all S/PDIF channels ( analog and optical ) with rates > 96K.

The S/PDIF Converter looses the lock , as seen in the S/PDIF STAT Register. It looses the lock frequently at 176K and always on 192K.

Also not even the word length is reported right at 192K.

Then we organized a ADSP-SC589-MINI board and this behaves the same on the optical input.

We just set the routing/pins in the DAI registers and the CTRL in the S/PDIF0 and read STAT to see if it is locking.

We use a professional signal source from audio-precision.

Any help would be welcome.
