I have a question about the PCM2902 chip; it's possible to use the same as analog audio to SPDIF converter without connect the same to a USB port ??? and powered it with an external 5V power supply ??.
No, unfortunately the PCM2902B cannot operate as a S/PDIF converter without the USB interface.
However, for that application, I would suggest checking out some of our digital audio interface parts. The DIR9001 (receiver) and DIX4192 (transceiver) both have S/PDIF conversion capabilities.
I tested the PCM2902 with sucess in recoding and reproducing audio files. However, I did not managed to get real time monitoring audio at the PC speakers when I am connecting a radio receiver at the input.
Apparently, the driver software does not allow me to set it for monitoring the input in real time. May you suggest something for such application?
