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
in
block-sized
buffers,
making
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
for or-
dering information.
Target applications include CD-R, DAT, MD, DVD and
VTR equipment, mixing consoles, digital audio trans-
mission equipment, high-quality D/A and A/D
converters, effects processors, and computer audio
systems.
