- Burst–Gate Output
- Horizontal Ramp Generator
- Internal Shunt Regulator
The NTE1739 is a video sync system in a 16–Lead DIP type package designed for use in television, monitor or video display products. The NTE1739 contains a horizontal phase–locked oscillator and vertical countdown. It also features composite blanking and burst–gate outputs which, when externally summed, produce the sandcastle pulse necessary for the operation of most chroma/luma circuits.
The NTE1739 is intended for use in 525–line systems and operates with standard or nonstandard input signals. An automatic mode–recognition circuit forces operation into the nonsynchronous mode
for nonstandard sync input signals.
