6) Video output in dark:Vd =
å
Vdn/Npixels
Note: In the dark means that sensor are placed on dark target and
measured with the light off.
7) Uniformity in the dark: Ud = (Vdmax-Vdmin)
Vdmax is the maximum pixel output voltage in the dark.
Vdmin is the minimum pixel output voltage in the dark.

Table 5. Recommended Operating Condition at Room Temperature
Note
1) Applies to both CP and SP.
2) See note 3 under Table 2.
3) Although the clock frequency will operate the device at less than 100KHz, it is
recommended that the device be operated above 500KHz. This recommendation is for
long module length, such as the A4 size with 27 sequentially cascaded sensors. The
long module at low clock rates has a long scan time. This results in a long photo
integration time that generates leakage currents. The leakage currents randomly store
arbitrary amounts of charges in the photo-site, contributing to the FPN in the dark.
