Evaluation Board for CS4384

Features

 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.

Description

The CDB4384 evaluation board is an excellent means

for quickly evaluating the CS4384 24-bit, 48-pin, 8-

channel, single-ended D/A converter. Evaluation re-

quires an analog signal analyzer, a digital signal source,

a PC for controlling the CS4384 (only required for con-

trol 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 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.
