CDB4382

Evaluation Board for CS4382

Features

! Demonstrates recommended layout and

grounding arrangements

! CS8414 receives S/PDIF, & EIAJ-340

compatible digital audio

! Headers for external audio input for either

PCMorDSD

! Requires only a digital signal source and

power supplies for a complete Digital-to-

Analog-Converter system

Description

The CDB4382 evaluation board is an excellent means

for quickly evaluating the CS4382 24-bit, eight channel

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

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

CS4382 (for control port mode only) and a power supply.

Analog line level outputs are provided via RCA phono

jacks.

The CS8414 digital audio receiver I.C. provides the sys-

tem timing necessary to operate the Digital-to-Analog

converter and will accept S/PDIF, and EIAJ-340 compat-

ible 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.
