1 About the Cheetah Camera
1.1 General
The Cheetah series of cameras are built around a robust imaging platform utilizing the
latest digital technology and components. The Cheetah C4080 and C2280 KAC camera
series is designed around two different CMOS imaging sensors featuring different
resolutions and frame rates. The cameras are available in monochrome and color.
This user manual provides information C4080 and C2880 cameras designed for Camera
Link Full output. The Cheetah family list is shown below:

Table 1: Cheetah C4080 and C2880 cameras overview.
The Cheetah cameras are advanced, intelligent, high-resolution, progressive scan, fully
programmable and field upgradeable CMOS cameras. They are built around the ON
Semiconductor area scan CMOS imagers and are feature rich with a built-in image
processing engine, low noise, and efficient and optimized internal thermal distribution.
The Cheetah cameras feature a wide range of programmable functions; including, dual
video options, extended dynamic range, exposure control, frame rate control, area of
interest, subsampling, pixel averaging, gain, offset, several triggering options, strobe
output control, transfer function correction, temperature monitoring and user
programmable and up-loadable LUT.
The user can program either a rolling shutter for the widest dynamic range or global
shutter for superior motion capture. The dual video mode allows two independent
acquisition frames (Frame A and Frame B) to be programmed with independent control of
exposure time, area of interest (AOI), subsampling, gain, offset and wide dynamic range
parameters. Additional controls support a variety of ways to seamless switch between
frames.
Exposure time for each frame can be controlled using an internal control or controlled by
an external pulse width. Exposure times up to 1 second with 1µs increments in rolling
shutter mode and 5µs increments in global shutter mode are supported. A custom AOI
can be programmed for each acquisition frame and subsampling or pixel averaging
capabilities are also available. Pixel averaging is a unique feature providing reduced noise
and improved signal to noise ratio by blending adjacent pixel information together.
Analog gains up to 12 dB (4x) in 12-bit digitization mode and 18 dB (8x) in 10-bit mode are
available. Digital gain controls allow further expansion of the low-end signal with 24dB

Cheetah KAC Camera User Manual | Camera Link (CLF) Interface
October 1, 2019 Page 9 of 135 Rev 7.2
(15.9x) of additional gain available. The wide dynamic range capability features multi-
integration times within one frame period compressing bright areas into the available
output range and extending the visible dynamic range up to 100db (global shutter mode
only) with up to 3 knee points.
A built-in Gamma correction and user-defined LUT capability optimizes the camera’s
dynamic range even further. Defective and hot pixel corrections can also be applied to
correct for pixels that are over-responding or under-responding. Auto-White Balance
(AWB) is available in color cameras to correct for color temperature. The cameras have a
Camera Link™ interface that includes 8/10/12 bits data transmission with two, four, eight
or ten output taps as well as camera control all on one or two cables. The cameras are
fully programmable via the Camera Link interface and support Power over Camera Link
(PoCL). The adaptability and flexibility of the camera allow it to be used in a wide and
diverse range of applications including machine vision, metrology high-definition imaging
and surveillance, medical and scientific imaging, intelligent transportation systems, aerial
imaging, character recognition, document processing and many more.

1.2 Cheetah Specifications
1.2.1 General Information
A CMOS camera is an electronic device for converting light into an electrical signal. The
camera contains a light sensitive element CMOS (Charge Coupled Device) where an
electronic representation of the image is formed. The CMOS image sensor consists of a
two-dimensional array of sensitive elements – silicon photodiodes, also known as pixels.
The photons falling on the CMOS surface create photoelectrons within the pixels, where
the number of photoelectrons is linearly proportional to the light level. Although the
number of electrons collected in each pixel is linearly proportional to the light level and
exposure time, the number of electrons varies with the wavelength of the incident light.
1.2.1.1 Global and Rolling Operations
Cheetah C4080 and C2880 cameras support both global and rolling shutter readout mode.
In Global Shutter (GS) mode, every pixel starts and stops integration at the same time.
This mode is excellent for clean capture of moving scenes without the need for a
mechanical shutter. When global shutter mode is used, all pixel data is stored in light
shielded regions within each pixel and held there until readout.
In Rolling Shutter (RS) mode, each line of the image sensor is captured at a slightly
different time. This can cause distortions in the image, if an object is moving very quickly
and the integration time is short with respect to the frame readout time. In rolling shutter
mode, pixels in a row are cleared of charge, allowed to integrate for the required
exposure time and then the entire line is readout. The resetting of each line ripples
through the array and each line is exposed with a slight time delay (equal to the line
readout time) relative to the previous line. In RS mode, the transistor within each pixel
used to provide global shutter capability is used to provide noise reduction.
Figure 1: Global Shutter Description.

Cheetah KAC Camera User Manual | Camera Link (CLF) Interface
October 1, 2019 Page 11 of 135 Rev 7.2
Figure 2: Rolling Shutter Description.
In Rolling Shutter (RS) mode, each line of the image sensor is captured at a slightly
different time. This can cause distortions in the image if an object is moving very quickly
and the integration time is short with respect to the frame readout time. In rolling shutter
mode, pixels in a row are cleared of charge, allowed to integrate for the required
exposure time, and then read out of the entire line. The resetting of each line ripples
through the array and each line is exposed with a slight time delay (equal to the line
readout time) relative to the previous line. In RS mode, the global shutter transistor in
each pixel provides noise reduction.
1.2.1.2 A/D architecture and Blooming Suppression
The ON Semiconductor KAC-12040 and KAC-06040 image sensors have an analog to
digital converter on each column and built-in correction circuits that automatically
compensate and correct for fixed pattern noise within the image array. With an A/D
converter on each column of the imaging array, digitization occurs within each line time
rather than within a readout pixel time, which improves noise performance. Two rows are
read out simultaneously (one from the top of the array and one from the bottom of the
array) and, in this manual, this is referred to as “one line.” While the camera has 3000
rows in the active image area, there are only 1500 lines read out and while the C2880
camera has 2128 rows, only 1014 lines are read out. The total number of rows including
overhead readout of the C4080 camera is 3136 (1568 lines) and the C2880 camera is 2292
rows (1146 lines) The camera takes care of all the details of re-ordering the lines within
frame grabber memory.
The A/D converter architecture allows the user to select between 10 or 12-bit digitization.
The Cheetah C4080 supports both 10 and 12-bit digitization. In 12-bit digitization mode,
the A/D conversion time is longer than the minimum chip readout time and this reduces
maximum frame rates. In 10-bit digitization the A/D conversion time is reduced increasing
the maximum frame rate. The image sensor provides up to eight LVDS readout banks and
the time to readout one line from the image sensor is less than the time necessary to
output the data using Camera Link. The camera compensates for this mismatch in data
output rates by adding additional delay at the end of each line.
Each pixel within the imaging array has extremely robust anti-blooming suppression
eliminating classic ‘black sun’ artifacts present in other CMOS imaging arrays. The CMOS

Cheetah KAC Camera User Manual | Camera Link (CLF) Interface
October 1, 2019 Page 12 of 135 Rev 7.2
readout architecture also eliminates column smearing often seen in traditional CCD image
sensors under extremely bright exposure conditions.
The time interval required for all pixels in the CMOS imager to clock out of the senson is
called a frame. To generate a color image, a set of color filters (red, green, and blue)
arranged in a Bayer pattern are placed over the pixels. The starting color is green. The
following illustrations show the CMOS image sensor architecture and spectral response of
the C4080 and C2880 cameras.

2.2 Camera Power and Data Connector
The male 12-pin Hirose connector provides power and all external input/output signals
supplied to the camera. Refer to the following Figure for connector pin-outs. Refer to the
Following Table for corresponding pin mapping. The connector is a male HIROSE type
miniature locking receptacle #HR10A-10R-12PB (71). The optionally purchased power
supply is shipped with a power cable which terminates in a female HIROSE plug #HR10A-
10P-12S(73).
The output interface requires a frame grabber for collecting and storing the camera’s
output. The frame grabber installs in the host computer. It enables you to view images
and configure the camera.
