Description
The CS7808 processor is a single chip solution that pro-
vides all of the processing functions you need for a broad
range of audio and video applications including thin me-
dia clients, CD recorders, advanced set-top boxes,
interactive TV and much more. It supports all CD for-
mats, disk control, video decoding and up to eight
channels of output. Achieve new levels of performance
with 240 highly configurable MIPS of processing power.
Its flexible set of design features maximizes perfor-
mance, reduces system complexity, and minimizes
system cost. CS7808 is the perfect choice.
Working on your next consumer entertainment product
design Combine CS7808 with other Cirrus mixed-sig-
nal converters, DSP chips, and factory firmware for a
highly integrated platform crucial for Video-on-demand,
set-top boxes, and other similar platforms. CS7808 is a
Total-E (Total Entertainment) IC solution specifically
designed for consumer entertainment electronics.
