Tint: Line scanning rate or integration time int is determined by the interval of two start pulses (SP). The module was test at 180us, but it will operate to 167us with
clocking speed of 5.0MHz.
f: main clock frequency he module was tested at 5.0MHz, but electrically it reliably operates above 5.0MHz, but with a minimum integration time of 167µsec.
Vpavg =
∑
Vp(n)/832
Up = [(Vpmax - Vp) / Vp] x 100% or [(Vp - Vpmin) / Vp] x 100%
Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)] x 100%
Upadj is the non-uniformity percentage pixel to pixel
Ud = Vdmax – Vdmin
Vdmin is the minimum output on a black document (O.D.=0.8)
Vdmax: maximum output voltage of black document (O.D.= 0.8)
MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]. DOF range is defined with the MTF
MTF is measured at glass surface and at 0.4mm from the glass > 50 percent and peaks at approximately mid-point of 0.2mm.
Vmax: maximum output voltage at 50 lp/inch (At 1/2 of the optical Nyquest Frequency)
Vmin: minimum output voltage at 50lp/inch
O.D. = optical density
lp / inch: line pair per inch
