3.0 Functional Description
The AMIS-710400-A4 imaging array consists of 27 sensors, which are cascaded to provide 3456 photo-detectors with their associated
multiplex switches and a digital shift register, which controls its sequential readout. Mounted in the module is a one-to-one graded
indexed micro lens array, which focuses the scanned documents to image onto its sensing plane. The on-board amplifier processes the
video signal to produce a sequential stream of video at the video output pin of the AMIS-710400-A4 module.
Illumination is accomplished by means of an integrated LED light source. All components are housed in a small plastic housing, which
has a cover glass, which acts as the focal point for the object being scanned and protects the imaging array, micro lens assembly and
LED light source from dust. I/O to the module is the 10-pin connector located on one end of the module (see Figure 4). The cross
section of the AMIS-710400-A4 is shown in Figure 1 and the block diagram in Figure 2.

Tint: line scanning rate or integration time. Tint is determined by the interval between two start pulses (SP).
f: main clock frequency, which also equals the video sampling frequency.
The video output level is controlled with LED current source.
Up = {[Vp(max) –Vp(min)]/Vp(max)}x100%
Where VP(max) = maximum peak pixel and VP(min) = minimum pixel.
Ud = Vdmax – Vdmin
Vdmin is the minimum output voltage with LED off.
Vdmax: maximum output voltage with LED off
This level is measured from the reset level, which is located between the pixels during the pixel reset duration. The reset level is at ground, 0V. It can be adjusted
with the offset potentiometer located on the module.
MTF = [(Vp(n) – Vp(n+1)] / (Vp(n)+ Vp(n+1)] x 100 [%]
Vp(n): nth maximum output pixel from a 8.0lp/mm target.
V(n+1)th: (n+1)th minimum output pixel from a 8.0lp/mm target.
lp / mm: line pair per mm

Note:
"Prohibit crossing of start pulse" is to indicate that the start pulse should not be active high between any two consecutive high going clock pulses or two consecutive low going
clock pulses (see Figure 3). Only one high going clock under the active high start pulse initiates the internal shift register, and it must not be active over two high going clocks.
All low going clock pulses will not initiate the shift register, but to ensure that the start pulse will not be actively high during two consecutive high going clocks, the circuit should
be designed to keep the start pulse active only for one low going clock cycle.
