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. The chip reports each line’s color burst phase
and frequency during the next horizontal sync pulse.
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.
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.
