Note: 3

This delay is necessary 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.

When at 0xxx xxxx, (HMoiré/HLock not selected), Pin 3 is a DAC with 0.3...2.75V range. When at 1xxx xxxx

(HMoiré/HLock selected) and PLL1 is locked, Pin 3 provides the waveform for HMoiré. See also Moiré

section.

Hjit = 106x(Standard deviation/Horizontal period).

Duty Cycle is the ratio between the output transistor OFF time and the period. The scanning transistor is

controlled OFF when the output transistor is OFF.
