NTE1547
Integrated Circuit
Video Chroma Deflection System
for Color TV
Description:
The NTE1547 combines the video鈥揷hroma subsystem and the deflection combination on a single
monolithic integrated integrated circuit to provide a color television video鈥揷hroma鈥揹eflection system.
This device includes a video amplifier, color demodulator that is designed to provide color differential
output, and improved sync鈥搒eparator, horizontal oscillator with saw tooth wave type AFC, horizontal
pre鈥揹river in a 42鈥揕ead DIP type plastic package.
