CCD Linear Image Sensor
MN3674
Color CCD Linear Image Sensor
with 512 Pixels for R and B Colors/1024 Pixels for G Color
s
Overview
The MN3674 is a high responsivity CCD color linear image sensor
with 512 pixels each for R and B and 1024 G pixels, and having low
dark output floating photodiodes in the photodetector region and
CCD analog shift registers for read out.
It can read a 64mm-width color document with a high quality and a
maximum pseudo resolution of 400dpi. In addition to being used as a
color sensor, this device can also be used as a black and white sensor
if only the G row is used, and in this case, it is possible to read a
64mm-width document with a full resolution of 400dpi. Since a one
line delay analog memory is built in so as to compensate for the
difference in the positions of reading out between the R, B rows and
the G row, the configuration of the signal processing circuit becomes
simpler.

Features
鈥?/div>
2048 floating photodiodes and n-channel buried type CCD shift
registers for read out are integrated in a single chip.
鈥?/div>
RGB primary colors type on chip color filters are used for color
separation.
鈥?/div>
In order to compensate for the distance between the photodiode
rows for the R, B colors and the G color, the device has a built in
analog memory that can store the signals of one line of the R-B
colors row.
鈥?/div>
All clock inputs can be driven by 5V CMOS logic.
鈥?/div>
Use of photodiodes with a new structure has made the dark output
voltage very low.
鈥?/div>
Large signal output of typically 0.8V at saturation can be obtained.

Application
鈥?/div>
Color graphic read out in color image scanners, color fax machines,
etc.
