General Description

The CS8420 is a stereo digital audio sample rate con-

verter (SRC) with AES3-type and serial digital audio

inputs, AES3-type and serial digital audio outputs, and

includes comprehensive control ability via a 4-wire mi-

crocontroller port. Channel status and user data can be

assembled

read/modify/write cycles easy.

Digital audio inputs and outputs may be 24, 20, or 16

bits. The input data can be completely asynchronous to

the output data, with the output data being synchronous

to an external system clock.

The CS8420 is available in a 28-pin SOIC package in

both Commercial (-10º to +70º C) and Automotive

grades (-40º to +85º C). The CDB8420 Customer Dem-

onstration board is also available for device evaluation

and implementation suggestions.

Please refer to

dering information.

Target applications include CD-R, DAT, MD, DVD and

VTR equipment, mixing consoles, digital audio trans-

mission

converters, effects processors, and computer audio

systems.
