NTE7049 Integrated Circuit CMOS–Sync Generator for TV & Video Processing Systems
Description: The NTE7049 is a CMOS LSI sync generator in a 24–Lead DIP type package 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/second TV camera or video processing system. A complete sync waveform is produced which begins each field 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.
