Notes:
(1) Tint: line scanning rate or integration time. Tint is determined by the interval of two start pulses (SP). See Note 2 for the high scanning speed operation.
(2) Fclk: main clock frequency. The call out is at 3.3MHz but electrically the module reliably operates to 5.0MHz. This modification will require adjusting the LED light
level and gain adjust.
(3) Vpavg = ∑ Vp(n)/1804
(4) Up = [(Vpmax - Vp) / Vp] x 100% or [(Vp - Vpmin) / Vp] x 100%
(5) Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)] x 100%
Upadj is the non-uniformity percentage pixel to pixel.
(6) Ud = Vdmax – Vdmin
Vdmin is the minimum output on a black document.
Vdmax is the maximum output voltage of a black document.
(7) MTF = [(Vmax - Vmin) / (Vmax + Vmin)] x 100 [%]. Depth of focus (DOF) range is defined with the MTF. MTF is the measure at the glass surface.
Vmax: maximum output voltage at 100lp/inch (At 1/2 of the optical Nyquest frequency)
Vmin: minimum output voltage at 100lp/inch
(8) lp / inch: line pair per inch

Notes:
(1) The clock high duration is at a 5.0MHz maximum clock rate.
(2) Tint (minimum) is the minimum line integration time available at a 5.0MHz clock rate. See Note 2 under Table 4.
