I have an audio project that currently uses a CS4334 DAC to provide L/R analog audio outputs from a digital I2S audio stream (from a STA013 mp3 decoder). I am trying to research SPDIF digital audio to see if I could support it as well. I have been googling for a while, but have not found any information on the physical line driving for SPDIF. Does anyone know of any good links for SPDIF digital audio? Does anyone know if there are line driver chips for SPDIF? Or, is it simple enough that it is done with discrete components?
