Notes:
(1)
Applies to all control-clock inputs.
(2)
Integration time is specified at room temperature such that the maximum dark current charge build up in each pixel is less than 10 percent of the minimum
saturation charge. Accordingly, it may be as long as 11 seconds at room temperature with the added capacitors. Longer integration times may be achieved by
cooling the device. An appropriate clock frequency must be chosen so that the shift register completes its operation within the desired integration time.

Notes:
(1)
Fill factor, quantum efficiency and responsivity are related by the equation R = (qel/hc).QE.FF.A, where qe is the charge of an electron and hc/l is the energy of a
photon at a given wavelength. Responsivity is therefore given per pixel.
(2)
At wavelength of 575nm (Yellow-Green) and with no window.
(3)
Measured at 50 percent Vsat with an incandescent tungsten lamp filtered with an Schott KG-1 heat-absorbing filter.
(4)
Saturation charge specified for a video output bias of 4.5V.
(5)
Max dark leakage 1.5 x average dark leakage measured with an integration period of 500ms at 25
°C.
(6)
From 250-1000nm, responsivity 20 percent of its peak value.
