Notes:
1. Tint is the line scanning rate or integration time. Tint is determined by the interval of two start pulses, SP. The integration time of 347µsec is set at the factory. For
additional comments, see Note (1) under Table 5.
2. fclk: main clock frequency.
3. Vpavg = ∑ Vp(n)/1728.
4. Up = [(Vpmax - Vpavg) / Vpavg] x 100% or [(Vpavg - Vpmin) / Vpavg] x 100%, where Vpmax = maximum pixel amplitude in the line scan and Vpmin = minimum
pixel amplitude in the line scan.
Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)) x 100%.
Upadj is the non-uniformity in percent between adjacent pixels, where Vp(n) is the n^th pixel in the line scan.
5. 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).
6. MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%].
Vmax: maximum output voltage at 50lp/in and Vmin: minimum output voltage at 50lp/in, where lp / in is the line pairs per inch.
