Camera Link Connector and Cable Configurations
A single Camera Link connection provides the following information on an MDR
connector with 26 pins.
This
configuration will transfer up to 28 bits of data. For applications that require more
bandwidth, additional Camera Link connections can be used.
There are 3 configurations – base, medium and full. Please visit the PULNiX
web site for detailed specifications of Camera Link.
Note: The MDR-26 cable assembly is manufactured by 3M Corporation.
Camera Link Cable Ordering Information
Camera Link cables are available from multiple vendors.
Channel Link Technology
The heart of Camera Link is Channel Link, a data transmission method by National Semiconductor. Channel Link
is made up of a receiver chip and a transmitter chip. This chipset is used to transmit digital data. This technology
offers many advantages to machine-vision applications over the previous method, namely, RS-644 (LVDS format of
RS-422).
LVDS (Low Voltage Differential Signaling) has become the most common means to transmit digital data in recent
years. This method, however, has several major drawbacks. LVDS requires a pair of wires for transmission of each
data bit, creating bulky cables prone to breakage if stressed. Also, the maximum data transmission rate of LVDS is
400 Mbps, fast enough for today’s applications, but limiting for tomorrow’s requirements. Channel Link takes LVDS
to the next level.
Channel Link uses LVDS standards to transmit data. Far fewer wires,
however, are needed to transmit the data. A Channel Link transmitter
will convert 28 bits of data into a format that can be transmitted over 4
parallel lines. A transmit clock over a fifth line finishes the requirements
for Channel Link transmission. The diagram to the right shows how just five
pairs of wire are able to transmit data that would require 56 wires using
standard LVDS methods.
