Summary Specification
KAI-2093 Image Sensor
DESCRIPTION
The KAI-2093 Image Sensor is a high-performance multi-
megapixel image sensor designed for a wide range of
medical imaging and machine vision applications.
The 7.4 µm square pixels with microlenses provide high
sensitivity and the large full well capacity results in high
dynamic range. The split horizontal register offers a
choice of single or dual output allowing either 15 or 30
frame per second (fps). The architecture allows for either
progressive scan or interlaced readout. The imager
features 5 V clocking to facilitate camera design. The
vertical overflow drain structure provides antiblooming
protection, and enables electronic shuttering for precise
exposure control.

There are 4 light shielded rows followed by 1084 photoactive rows and finally 4 more light shielded rows. The first and
last 2 photoactive rows are buffer rows giving a total of 1080 lines of image data.
In the single output mode all pixels are clocked out of the Video L output in the lower left corner of the sensor. The
first four empty pixels of each line do not receive charge from the vertical shift register. The next 28 pixels receive
charge from the left light shielded edge followed by 1928 photoactive pixels and finally 28 more light shielded pixels
from the right edge of the sensor. The first and last 4 photoactive pixels are buffer pixels giving a total of 1920 pixels
of image data.
In the dual output mode the clocking of the right half of the horizontal CCD is reversed. The left half of the image is
clocked out Video L and the right half of the image is clocked out Video R. Each row consists of 4 empty pixels
followed by 28 light shielded pixels followed by 964 photoactive pixels. When reconstructing the image, data from
Video R will have to be reversed in a line buffer and appended to the Video L data.

The horizontal shift register is on the side of the sensor parallel to the row of pins 1 through 16. In single output mode
the pixel closest to pin 1 will be read out first through Video L, the pixel closest to pin 17 will be read out last. In dual
output mode the pixel closest to pin 16 will be read out first through Video R.

Notes:
1. This value depends on the substrate voltage setting. Higher photodiode saturation charge capacities will lower the
antiblooming specification. Substrate voltage will be specified with each part for nominal photodiode charge capacity.
2. This is the first field decay lag at 70% saturation. Measured by strobe illumination of the device at 70% of photodiode
saturation, and then measuring the subsequent frame’s average pixel output in the dark.
3. Measured with a spot size of 100 vertical pixels.
4. Measured with F/4 imaging optics and continuous green illumination centered at 550 nm.
5. A blooming condition is defined as when the spot size doubles in size.
6. Antiblooming factor is the light intensity which causes blooming divided by the light intensity which first saturates the
photodiodes.

OPERATION NOTES
Progressive and Interlaced Timing
Progressive and interlaced output modes are achieved by the applying the proper waveforms to the vertical clock
input pins φV1, φV2E and φV2O. For progressive output, φV2 = φV2E = φV2O, with each of the 1092 lines read out
individually using the timing in Figure 9.
For interlaced output, there are two modes, field integration mode and frame integration mode. In both modes,
1092/2 = 546 lines are read in each frame readout, with one even frame readout and one odd frame readout necessary
for a complete frame. Field integration mode bins together alternate lines, and the timing is shown in Figure 11. As
with progressive readout, φV2 = φV2E = φV2O.
Frame integration mode reads out the photodiodes of the even and odd lines separately, and the timing is shown in
Figure 12. In this case, φV2E and φV2O are clocked individually.
Single Output Mode
When operating the sensor in single output mode all pixels of the image sensor will be shifted out the Video L output
(pin 31). To conserve power and lower heat generation the output amplifier for Video R may be turned off by
connecting VDDR (pin 24) and VOUTR (pin 18) to GND (zero volts).
The φH1 timing from the timing diagrams should be applied to φH1SL, φH1BL, φH1SR, φH2BR, and the φH2 timing
should be applied φH2SL, φH2BL, φH2SR, φH1BR. In other words, the clock driver generating the φH1 timing should
be connected to pins 4, 3, 13, and 15. The clock driver generating the φH2 timing should be connected to pins 2, 5, 12,
and 14.
The horizontal CCD should be clocked for 4 empty pixels plus 28 light shielded pixels plus 1928 photoactive pixels plus
28 light shielded pixels for a total of 1988 pixels.
DUAL OUTPUT MODE
In dual output mode the connections to the φH1BR and φH2BR pins are swapped from the single output mode to
change the direction of charge transfer of the right side horizontal shift register. In dual output mode both VDDL and
VDDR (pins 25, 24) should be connected to 15 V.
The φH1 timing from the timing diagrams should be applied to φH1SL, φH1BL, φH1SR, φH1BR, and the φH2 timing
should be applied to φH2SL, φH2BL, φH2SR, φH2BR. The clock driver generating the φH1 timing should be connected
to pins 4, 3, 13, and 14. The clock driver generating the φH2 timing should be connected to pins 2, 5, 12, and 15.
The horizontal CCD should be clocked for 4 empty pixels plus 28 light shielded pixels plus 964 photoactive pixels for a
total of 996 pixels.
If the camera is to have the option of dual or single output mode, the clock driver signals sent to φH1BR and φH2BR
may be swapped by using a relay. Another alternative is to have two extra clock drivers for φH1BR and φH2BR and
invert the signals in the timing logic generator. If two extra clock drivers are used, care must be taken to ensure the
rising and falling edges of the φH1BR and φH2BR clocks occur at the same time (within 3 ns) as the other HCCD clocks.
KAI-2093 Image Sensor
www.truesenseimaging.com Revision 1.0 PS-0026 Pg 19
EXPOSURE CONTROL
If the sensor is operated at 20 MHz horizontal CCD frequency then the frame rate will be 9 fps and the integration time
will be 1/9 s or 111 ms. To achieve shorter integration times, the electronic shutter option may be used by applying a
pulse to the substrate (pins 22 and 27). The time between the falling edge of the substrate pulse and the falling edge
of the transition of the φV2 clock from φV2H to φV2M is defined as the integration time. The substrate pulse and
integration time are shown in Figure 14.
Integration times longer than one frame time (111 ms in this example) do not require use of the electronic shutter.
Without the electronic shutter the integration time is defined as the time between when the φV2 clock is at the φV2H
level of 9.5 V (when the φV2 clock is at the φV2H level charge collected in the photodiodes is transferred to the
vertical shift register). To extend the integration time, increase the time between each φV2H level of the φV2 clock.
While the photodiodes are integrating photoelectrons the vertical and horizontal shift registers should be
continuously clocked to prevent the collection of dark current in the vertical shift register. This is most easily done by
increasing the number of lines read out of the image sensor. For example, to double the integration time read out
2184 lines instead of 1092 lines (but remember only the first 1092 lines will contain image data).
Depending on the image quality desired and temperature of the sensor, integration times longer than one second may
require the sensor to be cooled to control dark current. The output amplifiers will also generate a non-uniform dark
current pattern near the bottom corners of the sensor. This can be reduced at long integration times by only turning
on VDD to each amplifier during image readout. If the vertical and horizontal shift registers are also stopped during
integration time, the dark current in the shift registers should be flushed out completely before transferring charge
from the photodiodes to the vertical shift register.
DARK REFERENCES
There are 28 light shielded columns at the left and right side of the image sensor. The first and last two light shielded
columns should not be used as a dark reference due to some light leakage under the edges of the light shielding. Only
the center 24 columns should be used for dark reference line clamping. There are 4 light shielded rows at the top and
bottom of the image sensor. Only the center two light shielded rows should be used as a dark reference.
CONNECTIONS TO THE IMAGE SENSOR
The reset clock signal operates at the pixel frequency. The traces on the circuit board to the reset clock pins should be
kept short and of equal length to ensure that the reset pulse arrives at each pin simultaneously. The circuit board
traces to the horizontal clock pins should also be placed to ensure that the clock edges arrive at each pin
simultaneously. If reset pulses and the horizontal clock edges are misaligned the noise performance of the sensor will
be degraded and balancing the offset and gain of the two output amplifiers will be difficult.
The bias voltages on OG, RD, VSS and VDD should be well filtered with capacitors placed as close to the pins as
possible. Noise on the video outputs will be most strongly affected by noise on VSS, VDD, GND, and VSUB. If the
electronic shutter is not used then a filtering capacitor should also be placed on VSUB. If the electronic shutter is used,
the VSUB voltage should be kept as clean and noise free as possible.
The voltage on VSS may be set by using the 0.6 to 0.7 volt drop across a diode. Place the diode from VSS to GND. To
disable one of the output amplifiers connect VDD to GND, do not let VDD float.
The ESD voltage must reach its operating point before any of the horizontal clocks reach their low level. If any pin on
the sensor comes within 1 V of the ESD pin the electrostatic damage protection circuit will become active and will not
turn off until all voltages are powered down. Operating the sensor with the ESD protection circuit active may damage
the sensor.

Notes:
1. Long-term exposure toward the maximum
temperature will accelerate color filter degradation.
2. T=25 °C. Excessive humidity will degrade MTTF.
ESD
1. This device contains limited protection against
Electrostatic Discharge (ESD). ESD events may
cause irreparable damage to a CCD image sensor
either immediately or well after the ESD event
occurred. Failure to protect the sensor from
electrostatic discharge may affect device
performance and reliability.
2. Devices should be handled in accordance with
strict ESD procedures for Class 0 (<250V per
JESD22 Human Body Model test), or Class A
(<200V JESD22 Machine Model test) devices.
Devices are shipped in static-safe containers and
should only be handled at static-safe
workstations.
3. See Application Note Image Sensor Handling Best
Practices for proper handling and grounding
procedures. This application note also contains
workplace recommendations to minimize
electrostatic discharge.
4. Store devices in containers made of electro-
conductive materials.
COVER GLASS CARE AND CLEANLINESS
1. The cover glass is highly susceptible to particles
and other contamination. Perform all assembly
operations in a clean environment.
2. Touching the cover glass must be avoided.
3. Improper cleaning of the cover glass may
damage these devices. Refer to Application Note
Image Sensor Handling Best Practices.
ENVIRONMENTAL EXPOSURE
1. Extremely bright light can potentially harm CCD
image sensors. Do not expose to strong sunlight
for long periods of time, as the color filters
and/or microlenses may become discolored. In
addition, long time exposures to a static high
contrast scene should be avoided. Localized
changes in response may occur from color
filter/microlens aging. For Interline devices, refer
to Application Note Using Interline CCD Image
Sensors in High Intensity Visible lighting
Conditions.
2. Exposure to temperatures exceeding maximum
specified levels should be avoided for storage
and operation, as device performance and
reliability may be affected.
3. Avoid sudden temperature changes.
4. Exposure to excessive humidity may affect
device characteristics and may alter device
performance and reliability, and therefore should
be avoided.
5. Avoid storage of the product in the presence of
dust or corrosive agents or gases, as
deterioration of lead solderability may occur. It is
advised that the solderability of the device leads
be assessed after an extended period of storage,
over one year.
SOLDERING RECOMMENDATIONS
1. The soldering iron tip temperature is not to
exceed 370 °C. Higher temperatures may alter
device performance and reliability.
2. Flow soldering method is not recommended.
Solder dipping can cause damage to the glass
and harm the imaging capability of the device.
Recommended method is by partial heating using
a grounded 30 W soldering iron. Heat each pin
for less than 2 seconds duration.
