TDA4453
Video IF Amplifier for Multistandard TV Receiver and VTR
Appliances
Technology: Bipolar
Features
D Interference suppression
D Standard B/G-L suitable, processes negatively and
positively modulated IF-signals with equal polarity of
the output signal
D Ultra white inverter and ultra black limiter for
reducing transmission interference
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 interference
D 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
D Small differential error
D Constant input impedance
D Video output voltage with narrow tolerance
D Adapted output for insertion of ceramic transducers as
intrinsic sound trap
D Connecting and basic circuitry compatible to the
TEMIC video IF type programme - permits building
block system for video IF module
