NTE783
Integrated Circuit
Automatic Fine–Tuning Detector
Description:
Specifically intended for use in the automatic fine tuning (AFT) system of color television receivers,
the NTE783 AFT Detector provides all of the required circuitry except the tuning component. The
device embodies a high–gain input amplifier and automatic gain control (AGC) circuitry to provide ex-
cellent sensitivity in TV AFT systems employing low level IF amplifiers.
Features:
D Cascade–Cascode Amplifier
D Internal Voltage Regulator
D Internal AGC
D ±25kHz Frequency Deviation
D 14–Pin Dual In–Line Plastic Package
