CDB5331A
Evaluation Board for CS5330A / CS5331A
Features
• Demonstrates recommended layout
and grounding arrangements
• CS8402A Generates AES/EBU, S/PDIF,
& EIAJ-340 Compatible Digital Audio
• Buffered Serial Output Interface
• Digital and Analog Patch Areas
• On-board or externally supplied system
timing
General Description
The CDB5330A/31A evaluation board is an excellent
means for quickly evaluating the CS5330A/31A 18-bit,
stereo A/D converter. Evaluation requires a digital
signal processor, a low distortion analog signal
source and a power supply. Analog inputs are pro-
vided via RCA connectors for both channels.
Also included is a CS8402A digital audio interface
transmitter which generates AES/EBU, S/PDIF, and
EIAJ-340 compatible audio data. The digital audio data
is available via RCA phono, and optical connectors.
The evaluation board may also be configured to accept
external timing signals for operation in a user applica-
tion during system development.
