PL-D7715 Readout Timing

The readout timing of the sensor is as follows:

 maxFrameRate = 1 / minFrameTime
 minFrameTime = (Height/VerticalDecimation + VBmin) * tRow
 Where :
   VerticalDecimation is 1 if No Decimation is being applied
   VBmin = 146
   tRow = max{(Width/HorizontalDecimation + HBmin), 2352} * clkPeriod
   Where:
     HorizontalDecimation is 1 if No Decimation is being applied
     HBmin is 312
     clkPeriod is 1/220 MHz

If Triggering is not enabled and exposure time is greater than minFrameTime, then VB is increased in order to achieve the correct exposure time.  (ie maxFrameRate = 1/exposureTime)
