Description

The CDB4353 evaluation board is an excellent means

for quickly evaluating the CS4353 24-bit, high-perfor-

mance stereo D/A converter. Evaluation requires an

analog signal analyzer, a digital signal source, and a

+3.3 V 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.

The CDB4353 is controlled by switches to select the

digital signal source and configuration options for the

CS4353. Current sense resistors allow for easy power

calculations during system development.
