PRELIMINARY DATA SHEET CCD595 9216 x 9216 Pixel Image Area Full Frame CCD Image Sensor FEATURES • 9216 x 9216 Full Frame CCD Array • 8.75 µm x 8.75 µm Pixels • 80.64mm x 80.64mm Image Area • 100% Fill Factor • Non Multi-Pinned Phase (MPP) Operation • 8 Outputs (4 on each side) • Readout Noise Less Than 30 e- at 100MHz (25MHz x 4) GENERAL DESCRIPTION The CCD595 is a 9216 x 9216 active element solid state Charge Coupled Device (CCD) Full Frame sensor. 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 top of the package has an optical window over the CCD active area. The CCD595 is mounted in an environmentally sealed enclosure containing the CCD array with thermoelectric coolers for controlling the operating temperature of the array. Pinouts are provided on three sides for electrical connections (4output configuration). The package base serves as the heat sink interface for thermal management. A mounting flange at the package rim is used as a Z-axis reference datum for the planarization of the CCD focal plane with external optics. The output circuit architecture features eight (four active, eight optional) three stage source follower readouts. The nominal read noise of the output amplifiers is less than 25 electrons at 25MHz. The combined data rates for 4 and 8 output configurations are 100MHz and 200MHz respectively. Internal temperature and humidity sensors are also located near the FPA for external monitoring.

VGT VSRC COSMETIC GRADING Device grading helps to establish a ranking for the image quality that a CCD will provide. Blemishes are characterized as spurious pixels exceeding 10% of QSAT with respect to neighboring elements. Blemish content is determined in the dark, at various illumination levels and at different operating temperatures. The CCD595 is available in different grades, as well as custom selected grades. Consult Sales representative for available grading information and custom selections.
