Configuration Options
In hardware mode, to configure the CDB8422 for making performance measurements, one needs to use
the on-board control switches to set up the various components on the board. This section serves to give a
deeper understanding of the on-board circuitry and the digital clock and data signal routing involved in two
different hardware mode configurations of the CDB8422. These setups only serve as a starting point; the
switches can be further configured as needed (clock ratios, serial formats, etc).
AES3/EBU In to S/PDIF and PCM Out
The CS8422’s AES3/EBU receiver and SRC output performance can be tested by setting the hardware
switches as shown in Table 1 . This configures the digital clock and data signal routing on the board as
Digital AES3/EBU input is provided by the XLR jack J19 to the RXP0 and RXN0 pins of the CS8422. The
CS8422’s internal circuitry is configured to send the input audio data through its SRC to serial output port
1. This data is presented as PCM audio at header J24 and S/PDIF audio at J27 (coaxial) and J28 (optical).
The input data is also passed through (SRC is bypassed) to serial output port 2. This data is presented
as PCM audio at header J25. Refer to Section 3.3 for full details on hardware configuration.
