A negative or positive TTL level pulse applied on pin 2 (VSYNC) as well as a TTL composite sync on pin 1 can
Synchronize the ramp in the range [fmin, fmax]. This frequency range depends on the external capacitor
connected on pin 22. A capacitor in the range [150nF,
±
5%] is recommended for application in the following range:
50Hz to 185Hz.
Typical maximum and minimum frequency, at 25
°
C and without any correction (S correction or C correction), can
be calculated by:
f
(Max.)
= 3.5

fo and f
(Min.)
= 0.33

fo
If S or C corrections are applied, these values are slightly affected.
If a Synchronization pulse is applied, the internal oscillator is synchronized immediately but the amplitude changes.
An internal correction is activated to adjust it in less than a half a second: the highest voltage of the ramp pin 22 is
sampled on the sampling capacitor connected on pin 20 at each clock pulse and a transconductance amplifier
generates the charge current of the capacitor. The ramp amplitude becomes again constant.
The read status register enables to have the vertical lock-unlock and the vertical sync polarity informations.
It is recommended to use a AGC capacitor with low leakage current. A value lower than 100nA is mandatory.
A good stability of the internal closed loop is reached by a 470nF
±
5% capacitor value on pin 20 (VAGC)
