tw SYN C_IN T
The minimum w idth of the high pulse w hen the ―SMART EXSYNC‖

tTransfer The tim e from the recep tion of the falling ed ge of EXSYN C to the rising
ed ge of LVAL w hen p retrigger is set to zero. Pretrigger red uces the
number of clocks to the rising edge of LVAL but doesn‘t change the time
to the first valid p ixel. If the fixed integration tim e m od e of op eration is
available and selected then the integration tim e is ad d ed to the sp ecified
valu e. 1, 450 ±50 (2k)
1, 650 ±50 (4k)

Camera Output Format
There are several color output formats:
RGB m od e (interp olation): cam era ou tp u ts three colors (tw o native colors, one interp olated color) for
each p ixel.
RG/ BG m od e (native): In this m od e the cam era ou tp u ts tw o native colors p er p ixel, (RG or BG d ep end ing
on the p ixel location)
G m od e (native): This m od e p rovid es 100% fill factor nat ive green color that can be u sed as a
m onochrom e channel
