Table 4. S/PDIF Transceiver Window Controls
Table 5. USB Audio (Enable Window)
Table 6. USB Audio (Disable Window)
The S/PDIF block on the Digital Audio tab opens the
S/PDIF Transceiver window (Figure 6), which provides
controls for evaluating the U1 device with the on-board dig-
ital audio transceiver (U11). The digital audio transceiver is
hardwired to the U1 device’s S1 interface through header
JU13. See the Digital Audio Interfaces (S1, S2) section for
hardware details. The available controls and their descrip-
tions are listed in Table 4.
For the devices to automatically be configured, a signal
path and LRCLK frequency must be selected and the
Enable SPDIF and Autoconfigure CODEC checkboxes
must be checked. In addition, the master clock input
(MCLK) should be configured as instructed by the win-
dow’s displayed text. See the Master Clock (MCLK) section
for MCLK configuration options.
*This window only disables the USB audio playback. The U1
device configuration is not changed.

DESCRIPTION*
DESCRIPTION
Enables autoconfiguration of the CS8427 digital audio transceiver (U11).
When checked, it enables auto configuration of the U1 device. When not checked, the U1
device must be manually configured.
Provides three auto-configure options (Playback only, Record only, and Playback
and Record) used to auto configure the U1 and U11 devices (see below for signal path
details).
Provides LRCLK frequency options. Refer to the Clock Control section in the MAX9880A
IC data sheet.
Closes the window without making configuration changes.
Auto configures the U11 device (if Enable SPDIF is checked) or auto configures the
U1 device (if Autoconfigure CODEC is checked); autoconfigurations are based on the
Signal Path and LRCLK Frequency selections.
S/PDIF Audio
Figure 6. S/PDIF Transceiver Window
The USB block on the Digital Audio tab opens the USB
Audio window that either enables or disables audio
playback through the on-board USB stereo audio DAC
(U12), depending on the current enabled/disabled state.
This allows USB audio to be played through the U1
device. The USB stereo audio DAC is hardwired to the
U1 device’s S2 interface through header JU19. See the
Digital Audio Interfaces (S1, S2) section for hardware
details. The enable and disable window (Figures 7a and
7b) options are listed in Tables 5 and 6.
