High Performance Linear CMOS Image Sensors
ELIS CMOS IMAGER
Description
The ELIS Linear Image Sensor consists of an array of high performance low dark current photo-diode pixels. The
device features nearly the same performance characteristics of our LIS series of linear imagers, but also adds
sample and hold capability and the ability to bin pixels together. This in effect allows the user to select the devices
resolution. The device can operate at voltages as low as 2.8 VDC. A key feature over traditional CCD
technology, is that the device can be read and reread Non-Destructively, allowing the user to maximize signal to
noise and dynamic range.
Operation is simplified by on chip logic which requires only the user to select the bin resolution, input a cloc
k
equal to the desired pixel read rate, selecting the reset mode, and external reset to initiate read-out when running
asynchronously.
The ELIS imager is supplied in our exclusive PHOTO-SURF™ package. The package utilizes an optically clea
r
window, virtually eliminating distortion over that caused by traditional 'clear' plastic packages.
The Photon Vision Systems ELIS is a family of high performance linea
r
image sensor designed for a wide variety of applications as a superio
r
CCD replacement, including:
Edge Detection
Contact Imaging
Bar Code Reading
Finger Printing
Encoding and Positioning
Text Recognition

OPERATION AND TIMING
Resolution selection via binning.
Select the desired resolution with the following table;
M0 M1 Resolution Effective pixel size
0 0 1024 7.8 x 125 microns
1 0 512 15.6 x 125 microns
0 1 256 31.2 x 125 microns
1 1 128 64.4 x 125 microns
The effective imager length is 7.988 mm irregardless of the selected binned resolution. Internally, the device has 1024 pixels.
When the binned resolution is set to 512, pixels 1 and 2 photo diodes are averaged and output as a single pixel, pixels 3 and 4
are averaged and output as a single value, and so on. If set to 256 resolution, then pixels 1 through 4 are averaged and output
as a single value, 5 through 8 are averaged and output as a single value, and so on.
Absolute maximum ratings, T A = 25°C unless otherwise noted, see Note 1, below.
Supply voltage range, VDD------------------------------------------------ 0 V to 5.25 V
Digital input current range, I --------------------------------------------- –20 mA to 20 mA
Operating case temperature range, T C (see Note 2)------------------ –10°C to 70°
Operating free-air temperature range, T A -------------------------------- 0°C to 50°C
Storage temperature range ------------------------------------------------ –20°C to 85°C
Humidity range, Rh -------------------------------------------------------- 0-100%, non-condensing
Lead temperature 1.5 mm (0.06 inch) from case for 10 seconds----- 255°C
Exceeding the ranges specified under “absolute maximum ratings” can damage the device. The values given are for stress ratings only. Operation of the
device at conditions other than those indicated under “recommended operating conditions” is not implied. Exposing the device to absolute maximum rated
conditions for extended periods may affect device reliability and performance.
NOTES: 1. Voltage values are with respect to the device GND terminal.
2. Case temperature is defined as the surface temperature of the package measured directly over the integrated circuit.

TIMING
The device allows the user to control the integration time. Note – be sure to tie pin 4 (RM) to DGND.
Figure 1 - Start of Frame timing diagram.
Device Reset:
The first 2.0 µs as shown above indicate how to reset the imager. Both the RST input and the SHT input must be
simultaneously high for at least 1.0 µs to properly reset the imager. The imager can be held in reset indefinitely by keeping
both inputs high.
Integration:
Once RST input goes low, the pixel begins to integrate. Integration continues until SHT goes low. The diagram shows the
pixel integrating for 10.0 µs.
Readout:
Readout will then begin on the first rising edge of CLK after the DATA input is set high. DATA must be brought low prior
to the next rising CLK edge, otherwise pixel 1 is again output.
Binning:
By setting the M0 and M1 inputs as indicated in the Binning table above, different effective resolutions can be realized,
with the effective pixel area increasing in the table above. The internal control logic takes care that only one pixel is output
per CLK period. So if the imager is binned for 256 resolution, then only 256 additional clock cycles are needed to read out
the imager once DATA is set.
NOTES TO TIMING DIAGRAMS
1. Clock duty cycle should be 50%.
2. XXX Clock cycles for the number of pixels to read, starting at the first pixel.
3. t int represents integration time.
4. RST pulse always resets internal counter, thus next pixel output is the first pixel.
