The CCD is intended for advanced scientific, space, and aerial reconnaissance applications. The CCD595 is organized as an array of 9216 horizontal by 9216 vertical imaging elements. The pixel pitch is 8.75µm with a 100% fill factor. Three-phase clocking is employed in the imaging area with two-phase clocking in the serial readout registers. Image readout is performed via 4 serial registers containing 19 isolation rows between imaging and readout sections. The imaging array can be clocked unidirectional (4output configuration) or bi-directional (8-output configuration). The imaging area segments are split in mid-array for the latter configuration. To maximize the exposure/readout cycle rate, concurrent array and serial register clocking is utilized. Fast transfer clocking between the array and serial registers is accomplished with strapped transfer gates that load each line in less than 5 microseconds. The output circuit architecture features eight (four active, eight optional) three stage source follower readouts. The nominal re...
