(2) f: main clock frequency also equals the video sampling frequency.
(3) Video output level is controlled with LED current source.
(4) Up = {[Vp(max) –Vp(min)]/Vp(max)}x100%
Where VP(max) = maximum peak pixel and VP(min) = minimum pixel.
(5) Ud = Vdmax – Vdmin
Vdmin is the minimum output voltage with LED off.
Vdmax: maximum output voltage with LED off
(6) This level is measured from the reset level that is located between the pixels, during
the pixel reset duration. The reset level is at ground, 0V. It can be adjusted with offset
potentiometer located on the module.
(7) MTF = [(Vp(n) – Vp(n+1)] / (Vp(n)+ Vp(n+1)] x 100 [%]
Vp(n): n
th
maximum output pixel from a 8.0 lp/mm target.
V(n+1)
th
: (n+1)
th
minimum output pixel from a 8.0 lp/mm target.
(8) lp / mm: line pair per mm
