TDA4452
Overview
- Standard B/G-L suitable, processes negatively and positively modulated IF-signals with equal polarity of the output signal
- Fast AGC by controlled discharge of the AGC capacitor
- Ultra white inverter and ultrablack limiter for reducing transmission interference
- 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
- Internally noise protected gain control, no flyback pulses required
- Expanded video frequency response allows the demodulation of amplitude modulated MAC signals
- High input sensitivity
- Minimal intermodulation distortions
- Small differential error *
- Constant input impedance Video output voltage with narrow tolerance Video input/output for insertion of external sound trap VTR input/output with video switch Adjustable, delayed AGC for the tuner ESD protected Case: DIP18 Figure
