CX25871

www.DataSheet4U.com CX25870/871 Video Encoder with Adaptive Flicker Filtering and HDTV Output Conexant’s CX25870/871 is specifically designed to meet TV out system requirements for the next-generation desktop PCs, notebook PCs, game consoles and set-top boxes. With pin and software-forward compatibility to the Bt868/869, manufacturers can quickly bring to market new solutions that support adaptive flicker filtering, ATSC High-Definition Television (HDTV) output, and resolutions from 320 x 200 (minimum) to 1024 x 768 (maximum). Adaptive flicker filtering is a Conexant technology in which the encoder looks at the characteristics of the video content on a pixel-by-pixel basis and automatically determines the optimal amount of flicker filtering required. If an end-user wants to work on a spreadsheet while watching a DVD movie in a window, both the text-intensive application requiring a lot of flicker filtering and the DVD movie requiring very little flicker filtering can look their best. The amount of flicker filtering and overscan compensation is entirely flexible. The CX25870/871 also provides a 3-wire analog RGB or YPRPB HDTV output. While the encoder is in HDTV output mode, the device will automatically insert horizontal tri-level synchronization pulses and vertical synchronization broad pulses. The CX25870/871 is compliant with the EIA770-3, SMPTE 274M/293M/296M standards and supports ATSC HDTV resolutions including 480p, 720p, and 1080i. All worldwide standard definition o...
