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.

CDB5330A / CDB5331A CDB5330A/31A System Overview CS8402A Data Format The CDB5330A/31A evaluation board is an excellent means of quickly evaluating the CS5330A/31A. The CS8402A digital audio interface transmitter provides an easy interface to digital audio signal processors, including the majority of digital audio test equipment. The evaluation board has been designed to accept an analog input, and provide a digital output that is either optical or coax.

CDB5330A / CDB5331A The transceiver operates as a transmitter with the MASTER/SLAVE jumper in the MASTER position. LRCK, SDATA, and SCLK from the CS5330A/31A will be available on HDR2. HDR22 must be in the 0 position and HDR23 must be in the 1 position for MCLK to be an output and to avoid bus contention on MCLK. The transceiver operates as a receiver with the MASTER/SLAVE jumper in the SLAVE position. LRCK and SCLK on HDR2 become inputs.
