AMIS-722402: Contact Image Sensor
Data Sheet
Figures 10 to 13 show the timing of the SI/SO. At 2400dpi the SI/SO comes out in line with the 1367
th
pixel, at 1200dpi it comes out in
line with the 679
pixel, at 600dpi it comes out in line with the 335
pixel, and at 300dpi it comes out in line with the 163
pixel.
The SO from the first sensor enters as the SI clock of the second and subsequent sensors; hence all subsequent sensors will start their
register scan after each of the preceding sensors completes its scan.
The last active pixel of each sensor is the 1376
th
pixel for the 2400dpi mode, the 688
th
pixel for the 1200dpi mode, 344
th
pixel for the
600dpi mode, and 172
pixel for the 300dpi mode.
