tREADOUT Is the number of pixels per tap times the
readout clock period. Pretrigger = 0.
138033 (8K2T)
33, 792 (4K4T)
67,584 (4K2T)
33,792 (2K2T)
16,896 (1K2T)
tOVERHEAD Is the number of pixels that must elapse
after the falling edge of LVAL before the
EXSYNC signal can be asserted. This time
is used to clamp the internal analog
electronics
712+/-66
thPR Applies when the PRIN exposure control
feature is enabled . The PRIN signal must
be held a minimum time after the
EXSYNC falling edge to avoid losing the
integrated charge
0
twPR_LOW Minimum Low time to assure complete
photosite reset
2,640 +/- 264
tPR_SET The nominal time that the photo sites are
integrating. Clock synchronization will
lead to integration time jitter, which is
shown in the specification as +/- values.
The user should command times greater
than these to ensure proper charge
transfer from the photosites. Failure to
meet this requirement may result in
blooming in the Horizontal Shift Register.
2,640+/-264
2.8 Camera Link Serial Communication
Camera features can be controlled through the Camera Link™ serial communication
(LVDS, 9600 baud). The serial interface uses simple ASCII-based protocol. The following
chapter describes how to configure the camera using the serial interface.
