Small–Signal Subsystem for Color TV

Description:

The NTE7018 is a TV subsystem circuit intended to be used for base–band demodulation applica-

tions. This circuit consists of all small–signal functions (except the tuner) required for a quality color

television receiver. The only additional circuits needed to complete a receiver are a tuner, the deflec-

tion output stages, and a color decoder. The NTE1567 NTSC color decoder, and the NTE1754 verti-

cal output, are ideal complements for the NTE7018.

Features:

D Vision IF amplifier with synchronous demodulation

D Tuner AGC (negative–going control voltage with increasing signal)

D AGC detector for negative modulation

D AFC circuit

D Video preamplifier

D Sound IF amplifier, demodulator, and preamplifier

D DC volume control

D Horizontal synchronization circuit with two control loops

D Extra time constant switches in the horizontal phase detector

D Vertical synchronization (divider system) and sawtooth generator with automatic amplitude

adjustment for 50 or 60HZ

D Three level sandcastle pulse

Applications:

D Color television receiver

D CATV converters

D Base–band processing
