High Performance Linear Image Sensors
ELIS-1024 IMAGER
The Panavision SVI ELIS is a high performance linear image sensor designed to replace CCD’s in a wide
variety of applications, including:
• Edge Detection
• Contact Imaging
• Bar Code Reading
• Finger Printing
• Encoding and Positioning
• Text Scanning
P/N: ELIS-1024-LG
16-pin LCC package
Description
The ELIS-1024 Linear Image Sensor consists of an array of high performance, low dark current photo-diode
pixels. The sensor features sample and hold capability, selectable resolution and advanced power
management. The device can operate at voltages as low as 2.8V making it ideal for portable applications. 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. Internal logic automatically reduces power
consumption when lower resolution settings are selected. A low power standby mode is also available to
reduce system power consumption when the imager is not in use.
Key Features
• Low Cost
• Single Voltage Operation, Wide Operating Range
• Selectable Resolutions of 1024, 512, 256 and 128 pixels
• Intelligent Power Management and Low-Power Standby Mode
• Sample and Hold
• Full Frame Shutter and Dynamic Pixel Reset (DPR) Modes
• High Sensitivity
• High Signal to Noise
• Non-Destructive Read Capable, extremely low noise capable via signal averaging
• 1.0 kHz to 30.0 MHz Operation
• Very Low Dark Current
• Completely Integrated Timing and Control
• Replaces Entire CCD Systems, Not Just the Sensor

Resolution Selection
By setting the M0 and M1 inputs as indicated in Table 1, several effective resolutions can be realized.
The effective imager length is 7.987mm regardless of the selected resolution. Internally, the device
has 1024 pixels. As the resolution decreases the effective pixel area increases as in Table 1. When the
resolution is set to 512, the photodiodes of pixels 1 and 2 are averaged and output as a single value,
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. The internal control logic determines the resolution and always outputs a
valid pixel per clock cycle. For example, if the imager is selected for 256-pixel resolution, then only
256 clock cycles are needed to read out the imager once DATA is set. Thus, for lower resolutions
higher frame rates are possible as indicated in Table 1.

Power Management and Standby Mode
This device incorporates internally controlled power management features and an externally controlled
low-power Standby Mode. When resolutions lower than 1024-pixels are selected, internal logic
disables the unused amplifiers reducing the power consumption. Utilizing the existing external signals
RST and DATA a low-power Standby Mode is possible. When RST and DATA are simultaneously
held high the entire imager is put into Standby Mode. In this mode all internal amplifiers are disabled,
the internal clocks are stopped and the output amplifier is also disabled. The clock can be held low or
high or remain running while the imager is held in standby.

Dark Signal Non-Uniformity (DSNU))
Dark signal non-uniformity (DSNU), also known as
Fixed Pattern Noise (FPN), is a measure of pixel-to-
pixel variation when the array is in the dark. It is
primarily due to dark current differences, reset noise
and synchronous timing effects. It is a signal-
independent noise and is additive to the other noise
powers. The FPN associated with the sensor consists of
variations in pixel offset. Offset variations within any
pixel are inherently low due to the ACS technology.
Similarly, gain related FPN is almost non-existent due
the ACS technology. FPN is measured as a peak-to-
peak variation along a line of video averaged to remove
temporal noise.
Photo-Response Non-Uniformity (PRNU)
Photo Response Nonuniformity is pixel-to-pixel
variation in the response of an array to a fixed-intensity
light.
