NTE NTE700 Datasheet
NTE700
Integrated Circuit
TV Chroma System
Description:
The NTE700 is a monolithic integrated circuit in a 16–Lead DIP type package that performs the functions of subcarrier regeneration, ACC and APC detection, and tint control in color television receivers.
It is designed to function compatibly with the NTE743 TV Chroma Amplifier/Demodulator in a 2–package chroma system.
The NTE700 is a TV Chroma System equivalent to the NTE982 except that the typical supply voltage
is +12V and no internal shunt regulator is incorporated.
Features:
D Voltage–Controlled Oscillator
D Keyed APC and ACC Detectors
