Compatible Digital Audio
Headers for External PCM Audio
Requires Only a Digital Signal Source and
Power Supplies for a Complete Digital-to-
Analog Converter System
Description
The CDB4352 evaluation board is an excellent means
for quickly evaluating the CS4352 24-bit, high-perfor-
mance stereo D/A converter. Evaluation requires an
analog signal analyzer, a digital signal source, and a
power supply. Analog line-level outputs are provided via
RCA phono jacks.
The CS8416 digital audio receiver IC provides the sys-
tem timing necessary to operate the Digital-to-Analog
converter and will accept S/PDIF and EIAJ-340-com-
patible audio data. The evaluation board may also be
configured to accept external timing and data signals for
operation in a user application during system
development.
