TH7899M
2201A–IMAGE–02/02
General Description
The TH7899M sensor is a 2048 x 2048 full frame Charge Couple Device (CCD)
designed for a wide range of applications due to both its operating mode flexibility and
its high dynamic range combined with its high resolution. The device is 180° symmetri-
cal so if it is not plugged in the right side it will not be damaged.
The nominal photosensitive area is made up of 2048 x 2048 useful pixels split vertically
in 4 zones A, B, C and D. Each zone can be driven separately by four-phase clocks
(

Area” on page 3.
There are two identical horizontal shift registers: one at the top of the image area (regis-
ter A) and one at the bottom (register B). At each end of the two readout registers, a
summing gate is located which can be clocked to allow a horizontal pixel summation in
front of the on-chip output amplifier.
Applications
The TH7899M sensor is particularly suited to the following applications:
• Digital photography
• Medical applications
• Graphic arts
