AMIS-710228
Key Features
- The first of them is the printed
- circuit board (PCB) on which the 27 imaging chips, AMIS-720220 (PI3020), are bonded
- The chip-select switches are sequentially switched as each of the predecessor chips pletes its scan
- These 27 sensors, bonded on a PCB, are grouped into four sub-cascaded sections
- The first three sections VOUT1, VOUT2 and VOUT3 have seven sensor chips, while the VOUT4 has six sensor chips
- Since each sensor chip has 64 pixels, there are a total of 1728 pixels
- See Figure - AMI Semiconductor - May 06, M-20548-001 .amis
- It is a one-to-one graded indexed micro lens array that focuses the scanned documents' image onto the sensing line of the sensor chips
- The third major ponent, mounted in the module, is the LED light source
