Note: 1. Transients under 0.0V in the clock pulses will lead to charge injection, causing a localized increase in the dark signal. If such
spurious negative transients are present, they can be suppressed by inserting a serial resistor of appropriate value (typically
20 to 100Ω) in the corresponding driver output.

Notes: 1. V_OS = average video output voltage.
2. Fs = 2 F Φ_T. The minimum clock frequency is limited by the increase in dark signal.

Performance
General measurement conditions: T_C = 25°C; T_i = 1 ms; FΦT = 2.5 MHz (F_DATA = 5 MHz)
Light source: tungsten filament lamp (2854 K) + B6 38 filter (2 mm thick), F/3.5 aperture.
The filter limits the spectrum to 700 nm; in these conditions 1µJ/cm² corresponds to 3.5
lux.s.
Operating conditions (see Figure 1).
First and last pixels, as well as reference elements, are excluded from the specification.
Measurements taken on each output in succession.
