AMIS-722402: Contact Image Sensor
Data Sheet
Figures 8 and 9 detail the timing of the CLK, GBST, Vout, and SI/SO signals in further detail, which have the same timing requirements
for the 2400, 1200, 600, and 300dpi modes. The rise and fall times are listed in Table 6. In Figure 8, note that Pixel 76 is the first active
pixel, as the first 75 pixels are dummy pixels.
