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, along

with comprehensive control ability via a 4-wire microcon-

troller port. Channel status and user data can be

assembled in block sized buffers, making read/modi-

fy/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.

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

VTR equipment, mixing consoles, digital audio transmis-

sion equipment, high quality D/A and A/D converters,

effects processors and computer audio systems.
