High sensitivity
Low dark current and fixed pattern noise
Low read-out noise
Data rate up to 2 x 40 MHz
Mirrored and split read-out
The FTT 1010-M is a monochrome progressive-scan frame-transfer image sensor offering 1K x 1K pixels at 30 frames per second through a single output buffer. The combination of high speed and a high linear dynamic range (>12 true bits at room temperature without cooling) makes this device the perf ect solution for high-end real time medical X-ray, scientific and industrial applications. A second output can either be used for mirrored images, or can be read out simultaneously with the other output to double the frame rate. The device structure is shown in figure 1.

Frame Transfer CCD Image Sensor FTT1010-M

Architecture of the FTT1010-M

The FTT1010-M consists of a shielded storage section and an open image section. Both sections are electronically the same and have the same cell structure with the same properties. The only diff erence between the two sections is the optical light shield.
The optical centres of all pixels in the image section form a square grid. The charge is generated and integrated in this section. Output registers are located below the storage section. The output amplifiers Y and Z are not used in Frame Transfer mode and should be connected as not-used amplifiers.
After the integration time the charge collected in the image section is shifted to the storage section. The charge is read out line by line through the lower output register.
IMAGE SECTION
The left and the right half of each output register can be controlled independently. This enables either single or multiple read-out.
During vertical transpor t the C3 gates separate the pixels in the register. The letters W, X, Y and Z are used to define the four quadrants of the sensor. The central C3 gates of both registers are part of the W and Z quadrants of the sensor.
Both upper and lower registers can be used for vertical binning. Both registers also have a summing gate at each end that can be used for horizontal binning. Figure 2 shows the detailed internal structure.

During Charge Reset it is allowed to exceed maximum rating levels (see note5).

3
To set the VNS voltage for optimal Vertical Anti-Blooming (VAB), it should be adjustable between minimum and maximum values.
4
Three-level cloc k is preferred for maximum charge; the s wing during vertical transport should be 4V higher than the voltage during integration.
A two level clock (typically 10V) can be used if a lower maximum charge handling capacity is allowed.

• The typical CR level is applied to all image clocks simultaneously (preferred).
• The typical A-clock low le vel is applied to all image cloc ks; f or proper CR, an additional Charge Reset pulse on VNS is required. This will also aff ect the charge handling capacity in the storage areas.
