Features

• Demonstrates recommended layout

and grounding arrangements

• CS4328 Supports multiple input formats

• CS8412 Receives AES/EBU, S/PDIF,

& EIAJ-340 Compatible Digital Audio

• Digital and Analog Patch Areas

• Operation with on-board CS8412 or

externally supplied system timing

General Description

The CDB4328 evaluation board allows fast evaluation

of the CS4328 18-bit, stereo D/A converter. The board

provides an analog output interface via BNC connec-

tors for both channels. Evaluation requires an analog

signal analyzer, a digital signal source, and a power

supply.

Also included is a CS8412 digital audio receiver I.C.,

which will accept

AES/EBU,

S/PDIF, and EIAJ-340

compatible audio data.

The CS8412 can provide the

system timing necessary to operate the CS4328.

The evaluation board may also be configured to accept

external timing signals for operation in a user applica-

tion during system development.
