Timing Specifications
For all the modes detailed below, the
READOUT
is given as : NbPixels / (NbTaps * 40MHz)
The necessary delay between the end of integration and the beginning of the readout (tdr) is
calculated as 53 pixels at 40MHz :
tdr = 1,325µs
In the following timing diagrams, the line Period min is defined as :
LPmin = R tdr
Free Run
This mode doesn’t require an external trigger.
In this case, the line period (tper) can be defined in the Camera (see below) but the real line period of
the camera depends also on the exposure time (tint) set :
If tint > tper, the line period is equal to tint
If tper > tint, the line period is equal to tint
