... SL5067 VIDEO The video signal is applied to pin 4 via a coupling capacitor, (see Fig.9). This capacitor provides both clamping and black level hold. The internal peak white AGC can cope with an input signal of between 0.5 and 1.5 volts peak to peak.The full 9.5 dB AGC range is handled within a 600mV span on this storage capacitor ...

... POSITIVE MODULATION Several references are made in the text to positive video modulation and AM sound. Whilst it is possible to switch the device into these modes, it should be noted that the SL5067 will not perform to full SECAM specifications. Use of AM sound may produce sound–in–vision interference at higher modulation depths ...
