NTE842
Integrated Circuit
Television Video IF Amplifier,
Sync Separator, and AGC Processor
Description:
The NTE842 is a monolithic silicon integrated circuit in a 16–Lead DIP type package designed to per-
form IF amplification, tuner AGC, and composite sync–separation functions in color or monochrome
TV receivers.
PIN diodes are used in the IF amplifiers for gain control, resulting in increased dynamic range and
better signal–to–noise ratio.
Features:
D High–Gain Wide–Band IF Amplifiers
D Sample–and–Hold Keyed AGC
D Composite Sync Separator with Noise Immunity
D Fast AGC using PIN Diodes
D Gain Reduction with Excellent Stability
D Internal Varactor Pole Shift at Max Gain
