1. Tint: line scanning rate or integration time; tint is determined by the interval of two start pulses (SP). This integration time of 695µsec typically set at the factory for
Yyellow-Green LED. The minimum integration time of 347us is available at 5.0MHz pixel rate, but it will require optional light sources.
2. fclk: main clock frequency
3. Vpavg = ∑ Vp(n)/1728
4. Up = [(Vpmax - Vpavg) / Vpavg] x 100% or [(Vpavg - Vpmin) / Vpavg] x 100%
5. Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)] x 100%
Upadj is the non-uniformity in percent between adjacent pixels.
6. Ud = Vdmax – Vdmin
Vd = the average dark output level.
Vdmin is the minimum output on a black document (LED is turned off).
Vdmax: maximum output voltage of black document (LED is turned off).
7. MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]
Vmax: maximum output voltage at 50lp/in
Vmin: minimum output voltage at 50lp/in
8. lp / in: line pairs per inch

Note: Electrically, including the image sensors, the circuits will operate above 5.5MHz. However, with the Yellow-Green light option, the light exposure limits the operation to a
maximum of 3.0MHz, hence the integration time, tint of 0.576ms.
