Description

The CDB4354 evaluation board is a dedicated platform

designed to facilitate the evaluation of the CS4354 24-

bit, stereo D/A converter. Evaluation requires an analog

signal analyzer, a digital signal source, and a +5 V pow-

er 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 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 custom user application during system

development.

To accommodate various system configurations, sever-

al hardware controls and resistor population options are

provided. Current sense resistors allow for easy power

calculations during system development.
