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.
