Notes:
(1) Tint is the line-scanning rate or integration time and is determined by the interval between two start pulses (SP). The integration time is factory adjusted to give
1.25V output with the maximum clock frequency of 5MHz. However, a minimum integration of 630µs is with a maximum 5.5MHz clock frequency.
(2) Fclk is the main clock frequency and also equals the pixel rate.
(3) Video output level is dependent on the Integration time and the LED light power.
(4) Up = [Vp(max) - Vpavg] / Vpavg x 100% or [Vpavg - Vp(min)] / Vpavg} x 100%, whichever is greater.
Where Vp(max) = maximum pixel level, Vp(min) = minimum pixel level, and Vpavg = average of all pixels.
(5) Adjacent photo-response non-uniformity (Upn)
(6) Upn = Max ((Vpn – Vpn+1) / Min (Vpn, Vpn+1)) x 100%, where Vpn is the pixel output voltage of Pixel n in the light.
(7) Ud = Vdmax - Vdmin, where Vdmin is the minimum output voltage with the LED off and Vdmax is maximum output voltage with the LED on.
(8) See the paragraph in Section 9.0 for explanation.
(9) See the paragraph in Section 10.0. A graph of the typical MTF vs Depth of Focus is shown.
