AES3/EBU In to S/PDIF and PCM Out
The CS8422’s AES3/EBU receiver and SRC output performance can be tested by loading the “AES3 In
to SPDIF and PCM Out” quick setup file provided with the software package. The script configures the
digital clock and data signal routing on the board as shown in Figure 3 .
Digital AES3/EBU input is provided by the XLR jack J19 to the RXP0 and RXN0 pins of the CS8422. The
script configures the CS8422’s internal circuitry to send the input audio data through its SRC to serial out-
put 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 2.3 for details on software configuration.
