NTE1547
Integrated Circuit
Video Chroma Deflection System
for Color TV
Description:
The NTE1547 combines the videochroma subsystem and the deflection combination on a single
monolithic integrated integrated circuit to provide a color television videochromadeflection system.
This device includes a video amplifier, color demodulator that is designed to provide color differential
output, and improved syncseparator, horizontal oscillator with saw tooth wave type AFC, horizontal
predriver in a 42Lead DIP type plastic package.
Features:
