â1 The saturation signal level is 450mV or more by performing pull-down CSUB pin at 1.3k⦠resistor.
For high frame rate readout mode, it is 800mV.
â2 After closing the mechanical shutter, the smear can be reduced to below the detection limit by performing
vertical register sweep operation.
â3 Excludes vertical dark signal shading caused by vertical register high-speed transfer.
