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 sig-  
nals 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.  
The NTE7049 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 synchronized with a local on–chip crystal  
oscillator (the crystal and two passive components are off chip). Also, the circuit can sense the presence or  
absence of a reference sync pulse train and automatically select the “genlock” or “stand–alone” mode.  
A frame sync pulse is produced at the beginning of every odd field. The vertical counter can be reset to either  
the first equalizing pulse or the first vertical sync pulse of the vertical interval.
