NOTES:

2. Dynamic range is – 20 times the logarithm of the mean-noise signal divided by the saturation-output signal.

3. Charge-transfer efficiency is one minus the charge loss per transfer in the output register. The test is performed in the dark using

an electrical input signal.

4. Signal-response delay time is the time between the falling edge of the SRG pulse and the output-signal valid state.

5. VADC at 12 V and VSUBSTRATE at ground.

NOTES:

6. Based on 16.67 ms integration time.

7. Saturation is the condition in which further increases in exposure do not lead to further increase in output signal.

8. Blooming-overload ratio is the ratio of blooming exposure to saturation exposure.

9. Smear is a measure of the error introduced by transferring charge through an illuminated pixel in shutterless operation. It is

equivalent to the ratio of the single-pixel transfer time to the exposure time using an illuminated section that is 1/10 of the image-area

vertical height with recommended clock frequencies.

10. The exposure time is 16.67 ms, the fast dump clocking rate during vertical timing is 10 MHz, and the illuminated section is 1/10 of

the height of the image section.
