Notes:
1.
Tint stands for the line scanning rate or the integration time. It is determined by the time interval between two SPs.
2.
Fclk stands for the input clock frequency. For Fclk > 2.0MHz see Note 3 and the Section 5.
3.
Vpavg =
∑
Vp(n)/Npixels (average level in one line scan).
Where Vp(n) is the amplitude of n
pixel in the sensor chip and Npixels is the total number of pixels in sensor chip. Vpavg is converted from impulse current video
pixel into a voltage output (see Figure 4 and
4.
Figure
5
).
Exp = LP x Tint, where LP is light power (Yellow-Green) and tint is as defined above (see Figure 6).
5.
Up is the uniformity specification, measured under a uniform exposing light exposure. Up = [Vp(max) - Vpavg] / Vpavg x 100% or [Vpavg - Vp(min)] / Vpavg} x
100%, whichever is greater.
Where Vp(max) is the maximum pixel output voltage in the light.
Vp(min) is the minimum pixel output voltage in the light.
6.
Vd =
∑
Vp(n)/Npixels. Where Vp(n) is the pixels signal amplitude of the n
th
pixel of the sensor. Dark is where the sensor is placed in the dark environment.
7.
Ud = Vdmax – Vdmin. Dark is same definition as above.
8.
Upadj = MAX[ | (Vp(n) - Vp(n+l) | / Vp(n)) x 100%. Upadj is the non-uniformity in percentage. It is the amplitude difference between two neighboring pixels.
9.
Ucc is the uniformity specifications, measured among the good die on the wafer. Under uniform light exposure the sensors are measured and calculated with
following algorithm: Vpavg of all the good dies on the wafer are averaged and assigned VGpavg. Then the die with maximum Vpavg is assigned Vpavg(max),
and the one with minimum Vpavg is assigned Vpavg(min). Then UCC = {[Vpavg(max)-Vpavg(min)]/VGpavg}x100.
