TYPICAL SETUPS
ALL SETUPS
The switch and jumper settings in Table 5 are common for all
typical setups described in this user guide.

ANALOG INPUT AND ANALOG OUTPUT
Input comes from the stereo analog inputs to Pin ADC0 and
Pin ADC1 of the ADAU1401A and outputs on the DACs.
Default outputs for the ADC inputs are DAC outputs, VOUT2
and VOUT3.
In this setup, the master clock is generated by the ADAU1401A’s
oscillator connected to a 12.288 MHz crystal. Table 6 explains
how the switches and jumpers need to be set up for this mode.
Any component setting not mentioned in Table 6 or in Table 5
can be considered don’t care.
The settings in Table 5 and Table 6 are also appropriate for
using the serial data I/Os.

S/PDIF INPUT AND S/PDIF OUTPUT
Input comes from the stereo S/PDIF receiver to SDATA_IN0
(Pin 10) of the ADAU1401A and outputs on whichever outputs
(SDATA_OUTx) are designated in the SigmaStudio software.
The default output for the input is SDATA_OUT0 (Pin 15).
In this setup, the master clock and serial data clocks are
generated by the CS8416. Table 7 explains how the switches
and jumpers need to be set up for this mode. Any component
setting not mentioned in Table 7 can be considered don’t care.
