NTE701 Integrated Circuit Video Signal Processor Description: The NTE701 is a monolithic integrated circuit TV signal processor in a 16–Lead DIP type package designed for use in color or monochrome receivers. Circuit functions include a horizontal oscillator with AFC, a sync separator, and a key AGC system. The AGC system provides output signals for IF (reverse) and tuner (forward and/or reverse). The wide frequency–range horizontal oscillator has high stability at 503.3kHz.
