Thanks for your reply, but as a software person, I'm confused that you
mention the ADC (which I'm assuming is the analogue->digital converter).
  My question was about the digital optical input.

Or does the same chip handle both? Also, could you point me towards the
datasheet(s) you were referring to?

Thanks again,

Dave.
