TDA4452
Video IF Amplifier for Multistandard TV Receiver and VTR
Appliances
Technology:
Bipolar
Features
D
Standard B/G-L suitable, processes negatively and
positively modulated IF-signals with equal polarity of
the output signal
D
Fast AGC by controlled discharge of the AGC
capacitor
D
Ultra white inverter and ultrablack limiter for
reducing transmission interference
D
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
D
Internally noise protected gain control, no flyback
pulses required
D
Expanded video frequency response allows the
demodulation of amplitude modulated MAC signals
D
High input sensitivity
D
Minimal intermodulation distortions
D
Small differential error
