Integrated Circuit

Video Chroma Deflection System

for Color TV

Description:

The NTE1547 combines the video–chroma subsystem and the deflection combination on a single
monolithic integrated integrated circuit to provide a color television video–chroma–deflection system.

This device includes a video amplifier, color demodulator that is designed to provide color d ifferential
output, and improved sync–separator, horizontal oscillator with saw tooth wave type AFC, horizontal
pre–driver in a 42–Lead DIP type plastic package.

Features:
Video–Chroma Section

D Minimum number of external parts required
D Stabilized with respect to variation of temperature and supply voltage
D A few initial adjustments required

Deflection System

D Excellent temperature stability of horizontal oscillator
D Exact 50% duty cycle output due to the 2–fH oscillator and flip–flop circuit
D Excellent inter–race
D Stable sync separator with V/H input terminals.
