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.
