DIGITAL ROUTING OPTIONS

The WM8581 has extremely flexible digital interface routing options, which are illustrated in Figure 25.

It has a S/PDIF Receiver, S/PDIF Transmitter, four Stereo DACs, a Stereo ADC, a Primary Audio

Interface and a Secondary Audio Interface.

Each DAC has its own digital input pin DIN1/2/3/4. Internal multiplexers in the Primary Audio Interface

Receiver allow the data received on any DIN pin to be routed to any DAC. Any DIN pin routed to

DAC1 can also be routed to the S/PDIF transmitter and Secondary Audio Interface Transmitter.

DAC1 may also be used to convert received S/PDIF data, or data received from the Secondary Audio

Interface. DACs 2-4 take data only from the Primary Audio Interface. The Audio Interfaces can also

output ADC data or received S/PDIF data.

The S/PDIF transmitter can output S/PDIF received data, ADC data, or data from either Audio

Interface.
