QUICK REFERENCE DATA
Notes to the quick reference data
1. Pin 11 has a double function. When during switch-on a current of 9 mA is supplied to this pin, it is used to start the
2. On set AGC.
3. The output signal is measured at f = 7.5 kHz and maximum volume control.
4. The minimum value is obtained by connecting a 1.8 k resistor and a 470 nF capacitor in series between the video

supplied to this pin it can be used as a volume control.

results in a larger value of the minimum sync pulse amplitude). The slicing level is independent of the video
