Tint: Line scanning rate or integration time; tint is determined by the interval of two SP.
fclk: main clock frequency.
Vpavg =
∑
Vp(n)/2496; where n=1, 2, 3...., 2496.
Up = [(Vpmax - Vpavg) / Vpavg] x 100% or [(Vpavg - Vpmin) / Vpavg] x 100%, where Vpmax = the maximum V(n) and Vpmin = the minimum V(n).
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.
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.)
MTF = [(Vpmax - Vpmin) / (Vpmax + Vpmin)] x 100 [%]; tested on a 300 lp/inch target.
Vmax: maximum output voltage at 50lp/in and Vmin: minimum output voltage at 50lp/in, where lp/in is the line pairs per inch.

Note:
1.
Electrically, including the image sensors, the circuits will operate above 5.5MHz with tint at 455µs. However the light power is fixed, hence with the shorter
integration time, the exposure is reduced. This reduction limits the specification call out to integration time of 500µs at 5.0MHz for 1.0V output.
