1.0 CHEETAH FAMILY

The CHEETAH series of cameras are built around a robust imaging platform utilizing the latest
digital technology and components with CMOS imaging sensors, featuring different resolutions /
frame rates and available in both monochrome and color. The Cheetah family currently supports
Camera Link output. The CHEETAH series is programmable to support Camera Link Deca, Full,
Camera Link Medium and Camera Link Base depending upon the user’s needs.

This manual describes the C5180, C4181, C4180 and C3880 camera products which are listed
below using the Camera Link Output:

Table 1: Cheetah C5180, C4181, C4180 and C3880 Overview

1.1 GENERAL DESCRIPTION

The CHEETAH cameras are advanced, intelligent, high-resolution, progressive scan, fully
programmable and field upgradeable CMOS cameras. They are built around On
Semiconductors area scan Python 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, , exposure
control, frame rate control, area of interest, subsampling, pixel averaging, gain, offset,
several triggering options, strobes, output control, transfer function correction, temperature
monitoring and user programmable and up-loadable LUT.

All Cheetah cameras offer global shutter for superior motion capture and exceptionally high
frame rates for high thru-put applications. Cheetah camera exposure time can be controlled
using an internal control or controlled by an external pulse width. Exposure times up to 1
second with 1µs increments are supported. An Area of Interest (AOI) can be programmed
for each acquisition frame and subsampling or pixel averaging capabilities are also

available. Analog gains up to 10 dB (3.17x) are supported and digital gain controls allow
further expansion of the low-end signal with 24dB (16x) of additional gain available.

A built-in Gamma correction and user-defined Look-up Table (LUT) capability optimizes
the camera’s dynamic range even further. Defective pixel Correction (DPC) and hot pixel
correction (HPC) can also be applied to correct for pixels that are over-responding or under­responding. 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. 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.

1.3 CHEETAH SPECIFICATIONS

1.3.1 General Information

A CMOS camera is an electronic device for converting light into an electrical signal.
The camera contains a light sensitive element CMOS (Complementary Metal Oxide
Semiconductor) 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 amount of
electrons varies with the wavelength of the incident light.

CHEETAH Hardware User’s Manual

1.3.1.1 Global Shutter Description

All Cheetah cameras support global 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. (Figure 1.0)

Figure 1: Global Shutter Description

1.3.1.2 A/D architecture and frame rate controls

The C5180, C4181, C4180 and C3880 image sensors multiplex 80 (C5180), 64
(C4181 and C4180) and 60 (C3880) columns respectively into an array of 64 A/D
converters. The camera takes care of all the details of re-ordering the lines within
frame grabber memory. Unlike a CCD where digitization is performed within one
pixel time, these cameras perform digitize at 1/64th the pixel rate (64 A/D converters)
and the digitization has a depth of 10-bits

The image sensor provides up to thirty-two LVDS outputs and the time to readout one
line from the image sensor is much less than the time necessary to output the data
using Camera Link. The camera compensates for this mismatch in data output rate
versus data capture rate using two methods: a variable pixel clock for line readout and
the ability to add 1 micro-second of delay (row overhead) time at the end of each line
output by the camera. Slowing down the pixel line clock and adding delay (dead time)
at the end of each line allow the Camera Link grabber to keep pace with the camera
output.

1.5.3 Camera Link Physical Layer to Camera Link Receiver Bits

The timing diagram below describes how the Camera Link bits are transmitted over the physical
link. In the timing diagram below, X0, X1, X2 and X3 are the physical connections. Seven data
packets of four bits each are sent during each clock cycle and provide the 28 Camera Link Bits. In
the figure 8 below, Camera Link bits 0, 8, 19 and 27 are received over X0 to X3 in the first transfer
and bits 1, 9, 20 and 5 are received in the second transfer cycle. The timing for Y0 to Y3 and Z0 to
Z3 physical connections is the same as X0 to X3.

1.5.4 Camera Link Bit to Port Bit assignments

Tables 6-8 describe how the Camera Link Receiver bits received from X0-X3, Y0-Y3 and Z0-Z3
physical connections on CL connectors #1 and are translated into the Camera Link Port bits based
on the selected Camera Link Configuration: Base, Medium, Full or Deca.

1.6 MECHANICAL, OPTICAL, and ENVIRONMENTAL

1.6.1 Mechanical

The camera housing is manufactured using high quality zinc-aluminum alloy and
anodized aluminum. For maximum flexibility the camera has eight (8) M3X0.5mm
mounting screws, located towards the front and the back. An additional plate with ¼­20 UNC (tripod mount) and hardware is shipped with each camera.. All dimensions
are in millimeters.

1.6.2 Optical

The camera (72 x 72) mm cross-section comes with an adapter for F-mount lenses,
which have a 46.50 mm back focal distance.

The camera performance and signal to noise ratio depends on the illumination
(amount of light) reaching the sensor and the exposure time. Always try to balance
these two factors. Unnecessarily long exposure will increase the amount of noise and
thus decrease the signal to noise ratio.

The cameras are very sensitive in the IR spectral region. All color cameras have an
IR cut-off filter installed. The monochrome cameras come without IR cut filter. If

necessary, an IR filter (1 mm thickness or less) can be inserted under the front lens
bezel.

CAUTION NOTE

1. Avoid direct exposure to a high intensity light source (such as a laser beam).

This may damage the camera optical sensor!

2. Avoid foreign particles on the surface of the imager.

1.6.3 Environmental

The camera is designed to operate from -400 to 850 C in a dry environment. The
relative humidity should not exceed 80% non-condensing. Always keep the camera
as cool as possible. Always allow sufficient time for temperature equalization, if the
camera was kept below 00 C!

The camera should be stored in a dry environment with the temperature ranging
from -500 to + 900 C.

CAUTION NOTE

1. Avoid direct exposure to moisture and liquids. The camera housing is not

hermetically sealed and any exposure to liquids may damage the camera
electronics!

2. Avoid operating in an environment without any air circulation, in close

proximity to an intensive heat source, strong magnetic or electric fields.

3. Avoid touching or cleaning the front surface of the optical sensor. If the sensor

needs to be cleaned, use soft lint free cloth and an optical cleaning fluid. Do not
use methylated alcohol!
