AMIS-720658: Contact Image Sensor

Data Sheet

Figures 6 and 7 detail the timing of the CLK, GBST, Vout, and SI/SO signals in further detail, which have the same timing requirements

for both the 600 and 300dpi modes. The rise and fall times are listed in Table 5. In Figure 7, note that Pixel 83 is the first active pixel,

as the first 82 pixels are dummy pixels.
