NTE731
Integrated Circuit
TV Video Signal Processor
Description:
The NTE731 is an integrated circuit in a 16−Lead DIP type package and performs many of the func-
tions which are often collectively referred to as the video “jungle”. This device provides keyed AGC
for the tuner (forward and/or reverse) and the video IF (reverse), furnishes stripped synchronization
signals in both polarities, and provides low−impedance video and noise−cancelled video output
signals. The NTE731 is used as a low−cost, high−quality circuit in monochrome as well as color
TV receivers.
The circuit combines high performance with economy by eliminating the need for either AGC or
noise threshold adjustments. Positive noise gating and high sync. separator gain assure excellent
performance over a wide range of signal conditions.
