Case 2 - Exposure Start With Frame Valid Low
Figure 3-7: ExSync, Programmable Mode - Exposure Start with Frame Valid Low
If the ExSync signal falls while frame valid is low as shown in Figure 3-7:
• The actual start of exposure can be up to 11.5 µs later than the rise 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 programmed exposure time plus
77.7 µs minus the jitter time.
As shown in Figure 3-7, FVAL must be low for at least 1 µs before the ExSync signal
rises.
