CCD8091 9K x 128 Element TDI – Time, Delay and Integration Sensor FEATURES 9216 pixels per line Number of TDI stages electronically selectable: {4, 8, 16, 32, 64, 96, 128} Bi-directional TDI (shift up or down) 6 outputs — each capable of 20MHz data rate — 160MHz total data rate 100% fill factor 8.75µm x 8.75µm pixel size On-chip binning capability GENERAL DESCRIPTION The CCD8091 is a 9216 pixel x 128 line, high speed TDI sensor. The active imaging area is organized as 9216 vertical columns and 128 horizontal TDI rows. The array is set up for bi-directional operation. There are identical output registers and amplifiers on both the top and the bottom of the array. The outputs to be used (either top or bottom) are user-selectable and controlled by the vertical clock timing. In addition, the exposure level can be controlled by reducing the number of TDI rows from 128 to 96, 64, 32, 16, 8 or 4. This is also user-selectable and is accomplished by supplying the appropriate phasing for the vertical clocks within each section. For instance, if 64 lines of TDI were required, the vertical clocks for lines 65-128 would be connected to a high potential, which would drain these unused rows out to the opposite side (unused) of the array to be dumped into the VOFD drain. With six outputs, each running at 20MHz, the CCD8091 can provide a total data rate of 120MHz enabling the CCD to run at better than 12kHz line rate.
