5.1 CoaXPress interface
5.1.1 CoaXPress interface standard
The SP-5000M-CXP4 and SP-5000C-CXP4 use CoaXPress as their interface. CoaXPress is a PLUG-
AND-PLAY interface and connects the camera and the frame grabber board by coaxial cable(s). Its
maximum transfer rate is 6.25 Gbps per one coaxial cable. Additionally, CoaXPress interface
supports power supplied through the coaxial cable as well as communication signals. In the
CoaXPress interface, multiple coaxial cables can be used in order to achieve a faster transfer rate
or a reduced transfer rate can be used to extend the cable length.
In the SP-5000M-CXP4 and SP-5000C-CXP4, a 4 coaxial cable system is used.
Fig.3 CoaXPress interface
The distance between camera and frame grabber board depends on the bit rate of the video and
the cable used. Among the unique features of CoaXPress is its ability to supply DC power and provide
trigger timing accuracy.
The maximum power supply per one cable is 13W with DC+24V voltage. If the system uses 2 cables,
it will be 26W. The accuracy of the trigger is
±
2 ns at 3.125 Gbps.
The CoaXPress compliance labeling is assigned to the following five cable types and the maximum
bit rate and transmission length is indicated in the table below.

In the SP-5000M-CXP4 and SP-5000C-CXP4, the maximum bit rate is 6.25 Gbps per one cable and the
power supply is available on the CXP#1 connector only.
