Board Configuration Tab
The “Board Configuration” tab provides high-level control of signal routing on the CDB42L55. The controls
in this tab are used to setup the CS8416, CS8406, TxSRC, RxSRC and the FPGA Routing and are divided
into separate sections or control groups for each of these individual components. A description of each con-
trol group is outlined below. The software loads a predefined configuration when the selection is made from
the Quick-Setups section
FPGA Routing - Includes controls to setup the FPGA for using the S/PDIF or the PSIA test interface and for
setting up clock and signal routing for CS42L55 master/slave mode.
CS8416 S/PDIF Receiver Control - Register controls for setting up the CS8416.
CS8406 S/PDIF Transmitter Control - Register controls for setting up the CS8406.
CS8421 SRC Control - Register controls for the receive and transmit SRC’s. To configure, select the desired
SRC from the first drop down box and click update.
Update - Reads all registers in all devices and reflects the current values in the GUI.
Reset - Resets all devices to default configuration.
