Case 1 - Exposure Start With Frame Valid High
Figure 3-4: ExSync, Level-controlled Mode - Exposure Start with Frame Valid High
If the ExSync signal falls while frame valid is high as shown in Figure 3-4:
• The actual start of exposure can be up to 25 µs later than the fall of the ExSync signal.
(This is commonly referred to as an exposure start jitter.)
• The actual length of the exposure time will be equal to the ExSync signal low time plus
77.7 µs minus the jitter time.
As shown in Figure 3-4, FVAL must be low for at least 1 µs before the ExSync signal
rises.
