TMC2072 Datasheet Genlocking Video Digitizer

Manufacturer: Fairchild (now onsemi)

Overview: www.fairchildsemi.com TMC2072 Genlocking Video Digitizer.

General Description

The TMC2072 Genlocking Video Digitizer samples and quantizes standard analog baseband composite NTSC or PAL video into its 8-bit digital equivalent.

It extracts horizontal and vertical sync signals, from which an on-chip PLL generates a line-locked pixel clock for the on-chip 8-bit A/D converter and a double-speed register clock to transfer data to a subsequent video processing subsystem.

A second PLL generates a chroma subcarrier locked to the incoming chroma burst.
