Data interface
The Goldeye xy-008/032 camera models are available in two different data
interface versions, Camera Link Base and Gigabit Ethernet.
In the following paragraphs first the Camera Link interface is described. To bet-
ter understand the Gigabit Ethernet version it is important to note, that this
camera internally uses Camera Link compatible signals.
The adaptation to Gigabit Ethernet is done by a third party Camera Link frame
grabber that is inside the camera. Thus many of the properties mentioned in
conjunction with the Camera Link interface are also valid for the Gigabit
Ethernet interface version.
Camera Link interface
Camera Link is an interface for the transfer of digital video data. The standard
defines data transfer on a physical base and determines connectors, cables and
components for transmission and reception. Three different configurations
(base, medium and full) are available, distinguishing between the numbers of
parallel transferred data bits. While the base configuration is able to operate
with one cable, for the medium and the full configuration two cables between
camera and grabber are necessary.
The transmission components apply the so-called
Channel Link
technology.
28 parallel data bits each are serialized in a ratio of 7:1 and transferred in con-
nection with the clock signal via altogether five differential signal pairs. By
using LVDS, net clock rates up to 85 MHz can be achieved and cable lengths up
to 10 m are possible. Moreover four different control signals for camera control
(CC1 – CC4) from the grabber to the camera are available as well as a bi-direc-
tional serial communication channel that is also designed differentially. The
following drawing illustrates the Camera Link signals in the base configuration
that is used in the Goldeye CL-008/032 models.
