TDA4439
Overview
- Standard B/G-L suitable, processes negatively and positively modulated IF-signals with equal polarity of the output signal
- 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
- 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
- The direction of the AFC curve is selectable independently from the standard switch Case: DIP18 Figure
- Block diagram Rev. A1: 14.09.1995 1 (7) TDA4439
