... IF and tuner AGC The automatic control voltage to maintain the video output signal at a constant level is generated according to the transmission standard. Since the TDA9800 is suitable for negative modulation only the peak-sync level is detected. The AGC detector charges and discharges the capacitor on pin 19 to set the IF gain and the tuner gain. The AGC ...
