CoaXPress (CXP) is a simple yet powerful standard for moving high speed serial data from a camera to a frame grabber. Video is captured at speeds of up to 6.25 Gigabits/Second (Gb/S). Control commands and triggers can be sent simultaneously to the camera at rates up to 20 Mb/S (with a trigger accuracy of +/- 2 nanoseconds). Up to 13 W of power can also supplied to the camera. All of this happens over a single piece of industry standard 75 Ohm coaxial cable.
Multiple CXP links can be aggregated to support higher data rates (e.g. four links provide 25 Gb/S of data).
The CXP standard opens the door to applications where cable cost, routing requirements, and long distances have prevented the move to high resolution, high speed digital cameras. In many cases, existing coaxial infrastructure can be repurposed for CXP with very low installation costs.
The Karbon Platform
The Karbon platform has been shipped with a Camera Link front-end for many years. The acquisition and DMA engines have been tested under harsh industrial conditions, running 24/7, and has proven to be robust and reliable.
The Karbon CXP4 supports four CXP cameras or two two-link CXP cameras running up to 3.125 Gb/S or slower.
