Video IF Amplifier for Multistandard TV and VTR
Technology:
Bipolar
Features
Standard B/G-L suitable, processes negatively and
positively modulated IF-signals with equal polarity of
the output signal
Ultra white inverter and ultra black limiter for reduc-
ing transmission interference
Internally noise protected gain control, no flyback
pulses required
Expanded video frequency response allows the de-
modulation of amplitude modulated MAC signals
High input sensitivity
Fast AGC by controlled discharge of the AGC capacitor
Standard L mode: AGC acting on peak white level,
capacitor discharge control by averaged video signal
Standard B/G: AGC acting on the sync. pulse peak
The direction of the AFC curve is selectable indepen-
dently from the standard switch
Case:
DIP18
