Conexant CX23882
Preliminary Information
This document contains information on a new product. The parametric information, although not
fully characterized, is the result of testing initial devices.
CX23880/CX23881/CX23882/CX23883
PCI Audio/Video Broadcast Decoder
The CX23880/CX23881/CX23882/CX23883 decoders are a pin-compatible family of
highly flexible single chip solutions that enable television, radio, DTV, and broadband
data capture over the PCI bus.
CX23880 Distinguishing Features
Video Subsystem
The CX23880 family supports all analog broadcast video and audio formats used
worldwide today. This enables audio/video capture, video display, and audio playback on
the host PC, or storage and playback at a later time via software or hardware audio/video
codecs.
The CX23880 family is fully compatible with Conexant's family of digital channel
demodulators for capture of High and Standard Definition digital television streams and
broadband data over terrestrial, satellite, or cable links.
The CX23880 family supports a variety of third-party peripheral connectivity options via
its GPIO pins and CPU host port interface to enable board vendor-specific functionality
and market place differentiation.
