Description
The CDB8420 is designed to allow rapid evaluation of
the CS8420. Because of the high performance of the
CS8420, the board is set up for easy connection to an
Audio Precision or a Rohde and Schwarz test system.
Currently available A/D and D/A converters are not ade-
quate to test the full performance of the device.
Input and output data may independently be set to either
AES/EBU or S/PDIF in optical or coaxial physical
formats.
Windows 98 PC software provides a GUI interface to
make configuration easy. The software communicates
through the PC's RS232 port to a micro-controller on the
evaluation board that controls the CS8420. All the possi-
ble software modes of the CS8420 may be tested.
