CDB5381

Evaluation Board for CS5381

Features

Demonstrates recommended layout and

grounding arrangements

CS8406 generates S/PDIF, and EIAJ-340

compatible digital audio

Requires only an analog signal source and

power supplies for a complete Analog-to-

Digital-Converter system

Description

The CDB5381 evaluation board is an excellent means

for quickly evaluating the CS5381 24-bit, stereo A/D con-

verter. Evaluation requires a digital signal analyzer, an

analog signal source, and a power supply.

Also included is a CS8406 digital audio interface trans-

mitter which generates S/PDIF, and EIAJ-340

compatible audio data. The digital audio data is available

via RCA phono and optical connectors.
