CDB4391A
Evaluation Board for CS4391A
Features
z Demonstrates recommended layout and
grounding arrangements
z CS8414 receives AES/EBU, S/PDIF, &
EIAJ-340 compatible digital audio
z Digital and analog patch areas
z Requires only a digital signal source and
power supplies for a complete Digital-to-
Analog (D/A) converter system
Description
The CDB4391A evaluation board is an excellent means
for quickly evaluating the CS4391A 24-bit, stereo D/A
converter. Evaluation requires an analog signal
analyzer, a digital signal source, a PC for controlling the
CS4391A (for control port mode only) and a power
supply. Analog line level outputs are provided via RCA
phono jacks.
The CS8414 digital audio receiver IC provides the sys-
tem timing necessary to operate the D/A converter and
will accept AES/EBU, S/PDIF, and EIAJ-340 compatible
audio data. The evaluation board may also be config-
ured to accept external timing and data signals for
operation in a user application during system
development.
