Description
Pin 1,16 2 3,15 4 5 6 Function IF-input Standard switch: open B/G ground L Ground IF-AGC storage capacitor AGC (tuner control) Tuner AGC take over Pin 7 8,9 10 11 12 13 14 Function Not connected Demodulator circuit Average capacitor standard L Video output Not connected Supply voltage Not connected
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 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 Ultra white inverter and ultra black limiter for
reducing transmission interference
D Internally noise protected gain control, no flybac.
