TMC2072  
Genlocking Video Digitizer  
Features  
Description  
• Fully integrated acquisition  
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. The chip reports each line’s color burst phase  
and frequency during the next horizontal sync pulse.  
• 3-channel video input multiplexer  
• Two-stage (analog and digital) video clamp  
• Automatic gain adjustment  
• Sync detection and separation  
• Pixel and subpixel adjustment of video-to-sync output  
timing  
• Genlock to any NTSC or PAL format, including PAL-M  
and PAL-N  
• Pixel clock generation  
• 8-bit video A/D conversion  
The TMC2072 includes a three-channel video input multi-  
plexer, analog clamp, variable gain amplifier, and digital  
back porch clamp. The user may provide either an external  
20MHz clock or a 20MHz crystal. No external component  
changes or tuning are required for PAL or NTSC operation at  
either D1 or square pixel VGA pixel rates.  
• Standard R-bus serial microprocessor interface  
• User-selectable line-locked pixel rates include:  
– 12.27 MHz NTSC & PAL-M  
– 13.5 MHz NTSC & all PAL  
– 14.75 MHz PAL (non-M) TMC2072-1 only  
– 15.0 MHz PAL (non-M) TMC2072-1 only  
• Direct interface to Fairchild Semiconductor video  
encoders and decoders  
• Built-in circuitry for crystal oscillator  
• No tuning or external voltage reference required  
• Space-saving 100-lead MQFP package  
The TMC2072 is fabricated in a submicron CMOS process  
and is packaged in a 100-lead MQFP. Its performance is  
guaranteed from 0 to 70°C.  
Applications  
• Frame grabber  
• Digital videotape recorders  
• Desktop video
