DESCRIPTION
: Peripheral Imaging Corporation PI3039 CIS (Contact Image Sensor) sensor chip is a linear array image sensor chip with a 600 elements per inch resolution. Since this image sensor chip is intended for CIS module applications, multiple numbers of these sensors will be serially cascaded to form a linear scanning image array of arbitrary length. The sensors are mounted using the chip-onboard technology to form scanning arrays with various lengths 8080 µm 1 2 3 4 189 190 191 192 ROW OF 192 SENSORS AND VIDEO SIGNAL LINE MULTIPLEXER READ OUT SHIFT REGISTER 360 µm BUFFER BUFFER CHIP SELECT BUFFER SP CP VDD VSS IOUT EOS Figure 1. PI3039 Sensor Block Diagram Figure 1 is a block diagram of the sensor chip. Each sensor chip consists of 192 detector elements, their associated multiplexing switches, buffer amplifiers, and a chip selector. The detector's elementto-element spacing is approximately 42µm. The size of each chip without the scribe lines is 8080 µm by 360 µm. Each sensor chip has 6 bonding pads.
