Description
The CDB4382 evaluation board is an excellent means
for quickly evaluating the CS4382 24-bit, eight channel
D/A converter. Evaluation requires an analog signal an-
alyzer, a digital signal source, a PC for controlling the
CS4382 (for control port mode only) and a power supply.
Analog line level outputs are provided via RCA phono
jacks.
The CS8414 digital audio receiver I.C. provides the sys-
tem timing necessary to operate the Digital-to-Analog
converter and will accept S/PDIF, and EIAJ-340 compat-
ible 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.
