Sync Generator For TV Applications And Video Processing Systems

V The Harris CD22402 (Note) is a CMOS LSI sync generator that produces all the Timing signals required to drive a fully 2-to-1 interlaced 525-line 30-frame/second, or 625-line 25-frame/sec- ond TV camera or Video processing system. A complete sync waveform is produced which begins each eld with six serrated vertical sync pulses, preceded and followed by six half-width double frequency equalizing pulses. The sync output is gated by the master Clock to preserve horizontal phase continuity during the vertical interval. The CD22402 CAN be operated either in genlock mode, in which it is synchronized with a reference sync pulse train from another TV camera, or in stand-alone mode, in which it is syn- chronized with a local on-chip crystal Oscillator (the crystal and two passive components are off chip). Also, the circuit CAN By Harris Corporation
