EXT TRIG
The following equation is used for calculating the minimum trigger interval.
(Strobe delay 0 + Strobe Delay Time) + Strobe out (0 to1L) + 38L + 9L(OB) + Effective
2L + 1L
Whereby, Strobe delay 0 is inherent delay which is fixed at 35 clk ± 1ck,
Strobe delay time is determined by Strobe Enable Delay Time
Strobe out period is determined by Readout Begin Period
38L + (0 to 1L) + 9L(OB) and 2L+1L are fixed values.
Effective period may vary depending on scanning format.
