assuming 75 Ohm load resistor across the S/PDIF connector and a Voh out of the gates of 4.7V, which
typical Voh at 6mA.
C22 and C20 were added to the circuit to help meet RF compliance. However, they also band-limit the
S/PDIF signal, which increases jitter. D13 helps protect from over voltage or static shock.
