PI250MC-A6 Datasheet, PDF (3/7 Pages) AMI SEMICONDUCTOR – 200DPI CIS Sensor
This pictorial cross section shows the LED Bar light source and its Illumination path. The
light on the document reflects images on the document. The reflected images focus
through the micro lens onto the chips' image sensing line where images are converted to
proportional electrical charges. An on board amplifier processes these signal charges into
proportional video signal voltages, which is sent out to the output video port.
All components are housed in a small plastic housing and covered with a glass window.
This cover glass not only serves to protect all of the critical components within the housing
from dust, but, along with micro lens, it determines the depth-of-focus because it lies in
the optical path.
Pin Out Description
There is one connector located at the end of the module. The outline of the module in
Figure 4 of the mechanical section illustrates the connector location. With the module
window facing down on flat surface, with the viewer looking down on backside of the
module, and with the connector's pins facing viewer, the connector is located on the right
hand end of the module. The connector is a 1.25 mm single 10-pin row. Its I/O
designation is provided in Table 1. I/O Designation. Pin number 1 location is indicated on
the module outline.
