digital infotainment products PCl Audio/Video Broadcast Decoder CX23880/CX23881 Single-Chip Solution Allows TV, Radio, Digital TV and Broadband Data Capture Over the PCI Bus Conexants highly-flexible audio and video broadcast decoder supports all analog broadcast video and audio formats in use worldwide. This single-chip solution enables the host PC to perform audio/video capture, video display, audio playback, or storage and playback at a later time through software or hardware audio/video codecs. The CX23880/CX23881 is fully compatible with Conexants family of digital channel demodulators for capture of (HDTV) High Definition Television and Standard Definition Television (SDTV) streams, as well as broadband data over terrestrial, satellite or cable links. The CX23880 interfaces directly to the CX23490 HDTV hardware decoder for offloading the CPU of high-level MPEG-2 decoding tasks. Distinguishing Features A variety of third-party peripheral connectivity options are 10-bit video decoder supported by the CX23880/CX23881. Its General Purpose Input/ Adaptive comb filter Output pins and CPU host port interface enable vendor-specific Global broadcast audio decoder board functionality and marketplace differentiation. Stereo DACs Functional Overview 2 I S input and output The CX23880/CX23881 video and broadcast audio capture chip DTV and broadband support is a mixed-signal monolithic ic enabling a new platform for video, MPEG encoder and decoder interfaces audio, and data communications in the PC. The CX23880/CX23881 chips are designed to offer higher integration, functionality and are significantly more flexible and configurable than the previous generation Fusion 878A.digital infotainment products PCl Audio/Video Broadcast Decoder CX23880/CX23881 CX23880 Overview Level MPEG-2 decoding for DVB broadcast applications is supported via a dedicated MPEG port for streaming The CX23880 is designed to offer global support of compressed data streams to the host for software- for all analog video broadcast standards in based decompression. addition to digital broadcasts via an external channel demodulator. It is also designed to offload the CPU Both the CX23880 and CX23881 support a general of decoding tasks for High Level MPEG-2 (HDTV), purpose host port for connection to external CODECs 4:2:2 de-interlacing and progressive-scan DVD via for compression of analog video/audio broadcasts a dedicated ViP 2 Host Port interface to the CX23490 that can be stored on the hosts hard disk or played high-level MPEG-2 Decoder. back in software. CX23881 Overview Analog Video Capture Overview The CX23881 is a 100% pin-compatible and software- The CX23880/CX23881 integrates a 10-bit NTSC/ compatible subset of the CX23880. It is particularly PAL/SECAM composite and s-video decoder, image suited to the European marketplace and therefore resizer/scaler, Direct Memory Access (DMA) controller does not support BTSC-dBX and EIAJ audio as and Peripheral Component Interface (PCI) bus broadcast in the U.S. and Japan. In addition, the ViP master on a single device. The CX23880/CX23881 host port is not supported on the CX23881 as there is can place video data directly into host memory for no requirement for supporting high-level MPEG-2 video capture applications and into a target video decoding for digital television applications.
