PI409MC-A4 American Microsystems, Inc., PI409MC-A4 Datasheet - Page 6

• Manufacturer Part Number: PI409MC-A4
• Description: 400dpi CIS Module
• Manufacturer: American Microsystems, Inc.

MTF was measured with a 200 DPI or a 100 line-pair per inch optical bar pattern. The
test was conducted with pixel rate set to 2.5MHz.
The effective algorithm used in the measurements is as described by the following
equation:
MTF={[Vp(n)+Vp(n+1)]/2-[Vp(n+2)+Vp(n+3)]/2}/{[Vp(n)+Vp(n+1)]/2+[Vp(n+2)+Vp(n+3)]/2}
Where n is 1, 2, .....3456
Recommended Operating Conditions (25°C)
Note (1) see the note under the Table for Operating and Storage Environment.
Switching Characteristics (25°C)
The Switching Characteristics (25°C) for the I/O clocks are shown in the diagram Figure 4,
on the following page. For the timing symbol definitions see Table 6 below the timing
diagram. Note: Only one video output is shown because all four videos have identical
electrical characteristic. The only physical difference is in section 4 output,VOUT4.
Section 4 has only 6 sensor chips, hence, its active scan is shorter by 128 pixels.
