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 180µsec is set at the factory. For
additional comments, see Note 1 under Table 5.
(2) fclk: main clock frequency
(3) Vpavg = ∑ Vp(n)/3456
(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.
(5) 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.
(6) Ud = Vdmax – Vdmin
Vd = the average dark output level
Vdmin is the minimum output on a black document (LED is turned off).
Vdmax: is the maximum output voltage on a black document (LED is turned off).
(7) MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]
Vmax: is the maximum output voltage at 100lp/in (200dpi target) and Vmin: is the minimum output voltage at 100lp/in (200dpi target), where lp / in is the line pairs
per inch.
