TMC22071A - Fairchild Semiconductor

TMC22071A Genlocking Video Digitizer

The TMC22071A Genlocking Video Digitizer converts standard baseband composite NTSC or PAL video into 8-bit digital composite video data. It extracts horizontal and vertical sync signals and generates a pixel clock for the on-board 8-bit A/D converter and a 2x clock for the transfer of data to subsequent video processing decoding or encoding with the TMC22x5y.
