CDB4385A
Evaluation Board for CS4385A
Features
Description
Demonstrates recommended layout and
grounding arrangements
CS8416 receives S/PDIF, & EIAJ-340
compatible digital audio
Headers for external audio input for either PCM
or DSD
Requires only a digital signal source and power
supplies for a complete digital-to-analog
converter system
The CDB4385A evaluation board offers an easy way
for quickly evaluating the CS4385A 24-bit, 48-pin, 8-
channel D/A converter. Evaluation requires an analog
signal analyzer, a digital signal source, a PC for control-
ling the CS4385A (only required for control port mode),
and a power supply. Analog line-level outputs are pro-
vided 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.
