General Description
Peripheral Imaging Corporation’s PI6049A Contact Image sensor is a 600 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 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 344 active pixels, their associated multiplexing
switches, buffers, and an output amplifier circuit with a power down feature. The detector’s element-to-element
spacing is approximately 42.3 µm. The size of each sensor without the scribe lines is 14560 µm by 380 µm.
