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.
Features:
D Horizontal Oscillator with AFC
D Sync Separator with Noise Immunity
D Strobed AGC System
D IF AGC Output
D Delayed Outputs for Forward or Reverse AGC Tuners
D Internal Noise Threshold
D High–Impedance Video Input
D RF AGC Delay Externally Controlled
D Output Short–Circuit Protection
