Product Number: ADSP-SC589
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.
