TMC22071A Datasheet Genlocking Video Digitizer

Manufacturer: Fairchild (now onsemi)

Overview: .fairchildsemi. TMC22071A Genlocking Video Digitizer.

General Description

The TMC22071A Genlocking Video Digitizer converts standard baseband posite NTSC or PAL video into 8-bit digital posite 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 Video Decoder or TMC22x9x Digital Video Encoder family.

It also measures the color subcarrier phase and frequency and provides this data to the Encoder (for genlocked color NTSC or PAL encoding), or a frame buffer (for frame capture) over the digital posite video port.

Key Features

  • Fully integrated acquisition 3-channel video input multiplexer Two-stage video clamp Automatic gain adjustment Sync detection and separation Pixel and subpixel adjustment of HSYNC-to-Video timing Genlock to NTSC or PAL inputs Clock generation 8-bit video A/D converter Microprocessor interface Line-locked pixel rates - 12.27 MHz NTSC - 13.5 MHz NTSC or PAL Direct interface to TMC22x9x enc.
