General Description

Peripheral Imaging Corporation’s PI6050D Contact Image sensor is a selectable 600 or 1200 dot per inch (dpi)

resolution linear image sensor, which employs PIC’s proprietary CMOS Image Sensing Technology. The sensor

contains an on-chip output amplifier, power down circuitry and parallel transfer features that are uniquely

combined with the present-day active-pixel-sensor technology. The image sensors are designed to be cascaded

end-to-end on a printed circuit board (PCB) and packaged in an image sensing module. Applications for the

sensor array includes facsimiles, PC scanners, check readers, and office automation equipment.

Figure 1 is a block diagram of the sensor. Each sensor consists of 688 active pixels, their associated

multiplexing switches, buffers, and an output amplifier circuit with a power down feature. The sensors pixel-pixel

spacing is approximately 21.15

µm. The size of each sensor without the scribe lines is 14560 µm by 425 µm.
