Integrated Circuit
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
