Description
The CDB43122 evaluation board is an excellent means
for quickly evaluating the CS43122 or CS4397 24bit-
192 kHz D/A converters. The board accepts SPDIF and
SACD inputs and, with an analog output interface, pre-
sents line level signals via XLR connectors. Evaluation
requires an analog signal analyzer and a digital signal
source.
The CS8414 digital audio receiver I.C. provides the sys-
tem timing and data signals necessary to operate the
Digital-to-Analog converter and will accept AES/EBU,
SPDIF and EIAJ compatible audio data. The evaluation
board may also be configured to accept external timing
signals for operation in a user application during system
development in PCM and DSD modes.
