This delay is mandatory to avoid a wrong detection of polarity change in the case of a composite sync.
See Figure 10 for explanation of reference phase.
These parameters are not tested on each unit. They are measured during our internal qualification.
A larger range may be obtained by application.
Hjit = 10
Duty Cycle is the ratio between the output transistor OFF time and the period. The power transistor is
controlled OFF when the output transistor is OFF.
