This capacitor should be 100 nF film type to give good
temperature stability.
The potentiometer at Pin 2 adjusts the free running
frequency of the oscillator. It should normally be set
for about 55 Hz with no vertical signal input such that
it will lock to 60 Hz.

composite sync input should consist of –VE sync
signal only with amplitude > 500 mVpp.
The source impedance of the sync signal should be
<1.0 kΩ.
Sync information at Pin 5 will override this pin, but
signals at Pin 4 will not.
Minimum pulse width is 2.0 µs.
