SensorInClock 74.25 ( MHz Pixel clock)
NumberOfLVDS 2
20.2.3.1 Free running mode
In free running mode, the sensor reaches its maximum frame rate. This is done by overlapping
erase, exposure and readout phase. The sensor timing in free running mode is fixed, so there is no
control when to start an acquisition. This mode is used with trigger mode Continuous.
To calculate the maximum frames per second (FPS
max
) in free running mode you will need following
formula:
InternalLineLength * 8 ImageHeight + VerticalBlankLines
FrameTime = ------------------------------ * ----------------------------------
SensorInClock * NumberOfLVDS 1000
If exposure time is lower than frame time:
1
FPS_max = ------------
FrameTime
If exposure time is greater than frame time:
1
FPS_max = --------------
ExposureTime
20.2.3.2 Frame rate calculator
Note:
The calculator returns the max. frame rate supported by the sensor. Please keep in mind
that it will depend on the interface and the used image format if this frame rate can be
transferred.

Image bit depth:
10 bit / 8 bit
12 bit
Pixel clock: 74.25 MHz
Image width: pixels
Image height: pixels
Exposure time: us
Frame rate (max): 1/s
ExposureTime > FrameTime → FPS = 1 / ExposureTime
Note:
The exposure time step width is limited to the sensor's row time of 4.86 us and therefore
- auto exposure with very low exposure times will perform with relatively large increments
and
- exposure mode = TriggerWidth (if available) will perform with a jitter corresponding to the
row time
