The NTE1739 is a video sync system in a 16Lead DIP type package designed for use in television, monitor or video display products. The NTE1739 contains a horizontal phaselocked oscillator and vertical countdown. It also features composite blanking and burstgate 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 525line systems and operates with standard or nonstandard input signals. An automatic moderecognition circuit forces operation into the nonsynchronous mode for nonstandard sync input signals. Absolute Maximum Ratings:
