2.3 ANTI-BLOOMING BY CLOCKING
Anti-blooming can be activated or inhibited (see 2.5.3) :
♦ anti-blooming OFF : this position is recommended if anti-blooming is not required for the application.
♦ anti-blooming ON : anti-blooming operation reduces the pixel saturation charge. As a consequence, camera
gain must be set to 1.30x (see 2.5.3) minimum in order to reach the camera saturation level (4095 adu)
2.4 ELECTRICAL INTERFACES :2.4.1 POWER SUPPLY :

+24V
Min : +20V ; Max : +28V 0.6A
2.4.2 DIGITAL I/O
SYMBOL I/O DEFINITION LEVEL
TRIG_ITC ITiming control :
TRIG_ITC is either an external trigger or “ integration time control ”
depending on the timing mode configurated by RS232 (see after)
operation with external trigger :
TRIG_ITC = TRIG
operation with “ integration time control ” :
TRIG_ITC = ITC
TRIG_ITC is synchronized by the camera line clock (jitter : 200 µs)
LVDS
S(11..0) ODigital video output : 12 bits LVDS
FEN Frame enable :
- FEN = 0 : frame data valid : active lines
- FEN = 1 : frame data not valid
LVDS
LEN OLine enable :
- LEN = 0 : line data valid : active pixels
- LEN = 1 : line data not valid
LVDS
PCK OPixel clock LVDS
SHUTTER Oshutter open/close :
- during integration : shutter = 1
- during readout : shutter = 0
delay between the falling edge of shutter and the start of readout :
- 4 positions : 1ms, 5ms, 10ms, 20ms.
