Notes:
• DSD0A and DSD0B output must be used when in stereo mode only. DSD0A and DSD0B
always carry the main 2-channel audio data.
• DSD1A, DSD1B, DSD2A, and DSD2B are the surround channels.

The I S and DSD interfaces share the same pins. By default, the ADV7604 automatically enables the
DSD interface if it receives DSD packets. The ADV7604 also automatically enables the I
if it receives audio sample packets or if it does not receive any audio packets. However, it is possible
to override the audio interface that is used via the
MUX_DSD_OUT controls.
