AMIS-720649: Contact Image Sensor Data Sheet 1.0 General Description AMI Semiconductor’s AMIS-720649 (PI6049A) contact image sensor (CIS) is a 600 dots per inch (dpi) resolution linear image sensor, which employs AMI Semiconductor’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 include 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 42.3µm. The size of each sensor without the scribe lines is 14560µm by 380µm. 2.0 Block Diagram 14560µm 42.3µm 1 2 3 4 Row of 344 Pixels and Video Line Multiplexer 341 342 343 344 Parallel Transfer, Storage Cells and Readout Registers 380µm www.DataSheet4U.com Amplifier, PowerDown and Offset Control SI SIC CLK AVDD DVDD AVSS DVSS VOUT OR OS VR SO GBST Figure 1: Sensor Block Diagram AMI Semiconductor – Dec. 05, M-20488-001 www.amis.com 1 AMIS-720649: Contact Image Sensor 3.0 Key Features 600dpi 344 i...
