3.5.3 AP PSIA Interface

The input-USB board provides the ability to input I2S directly into the PurePath EVM. I2S source could be,
for example, an Audio Precision with a Programmable Serial Interface Adaptor (PSIA).
Default jumper settings are shown in
routed to Data1, analog channels 3 and 4 to Data2, etc., when analog inputs are selected. When digital
input is selected, either coax or TosLink channel A+B is copied into all data outputs.
When using the input-USB board with an external I2S source connection, the jumper settings in
should be used. Placing the jumper as shown copies I2S data into all data outputs.
