... Functional Overview The CX23880/CX23881 video and broadcast audio capture chip is a mixed-signal monolithic ic enabling a new platform for video, 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 ...

... CX23880 particularly suited to the European marketplace and therefore does not support BTSC-dBX and EIAJ audio as broadcast in the U.S. and Japan. In addition, the ViP host port is not supported on the CX23881 as there is no requirement for supporting high-level MPEG-2 decoding for digital television applications. Main Feature ...

... PCI bus to stream data as soon as the bus is available, thereby avoiding the need for on-board frame buffers. The CX23880/CX23881 contains a pixel data First In, First Out (FIFO) to decouple the high-speed PCI bus from the continuous video data stream. The video data input may be scaled, color translated, and burst-transferred to a target location on a field basis ...

... Conexant Application Engineering for a list of supported third-party video compressors. ITU-R 656/VIP 2.0 Pixel Data Input The CX23880/CX23881 provides a 27 MHz, 8-bit ITU-R 656 decoded video input interface to allow a third-party MPEG-2 decoder or codec to send 4:2:2 data over the PCI bus to a target video display frame buffer for video overlay. ...

... The third concept is for the host to be able to access register space on connected VIP slave devices. The CX23881 does not support the VIP 2.0 host master interface port and in order to retain pin compatability with the CX23880, these pins are configured as GPIO. ...
