CDB5343: Evaluation Board for CS5343
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 Supply for a Complete Analog-
to-Digital Converter System
Description
The CDB5343 evaluation board is an excellent
means for quickly evaluating the CS5343 24-
bit, stereo A/D converter. Evaluation requires
a digital signal analyzer, an analog source,
and a power supply.
Also included is an CS8406 digital audio inter-
face transmitter that generates S/PDIF and
EIAJ-340-compatible audio data. The digital
audio data is available via RCA phone and op-
tical connectors.
