I/O
SYMBOL I/O DEFINITION LEVEL
TRIG_ITC I Timing 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 : 62 µs)
LVDS
COLOUR_I(1..0) I Colour selection of the next frame (in color mode) :
- "00" : red
- "01" : green
- "10" : blue LVDS
S(11..0) O Digital video output : 12 bits LVDS
FEN Frame enable :
- FEN = 0 : frame data valid : active lines
- FEN = 1 : frame data not valid LVDS
LEN O Line enable :
- LEN = 0 : line data valid : active pixels
- LEN = 1 : line data not valid LVDS
PCK O Pixel clock LVDS
COLOUR_O(1..0) O Color identification of the current frame (in color mode) :
- "00" : red
- "01" : green
- "10" : blue. LVDS
SHUTTER O shutter 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. LVDS
