TDA4453
Overview
- Interference suppression
- 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 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
- Ultra white inverter and ultra black limiter for reducing transmission interference
- Internally noise protected gain control, no flyback pulses required
- Expanded video frequency response allows the demodulation of amplitude modulated MAC signals *
- Small differential error Constant input impedance Video output voltage with narrow tolerance Adapted output for insertion of ceramic transducers as intrinsic sound trap TEMIC video IF type programme - permits building block system for video IF module
- High input sensitivity
- Minimal intermodulation interference
- Connecting and basic circuitry compatible to the Figure
