Description

The CDB4350 evaluation board is an excellent platform

for quickly evaluating the CS4350 24-bit, 24-pin, stereo

D/A converter. Evaluation requires an analog signal an-

alyzer, a digital signal source, a PC for controlling the

CS4350 (only required for Control Port Mode), 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-compatible audio da-

ta. The evaluation board may also be configured to

accept external timing and data signals for operation in

a user application during system development.
