CoaXPress (CXP) is a digital interface standard developed for high-speed image data transmission in machine vision applications.
Some recent CoaXPress cameras and frame grabbers use 8 coaxial cables providing a maximum image data rate of about 48 GB/s.
Unlike Camera Link (which is built upon pure LVDS with no transport layer), CoaXPress transmits data in packets using 8b/10b encoding and provides CRC.
CoaXPress was developed by 6 companies, of whom Adimec, EqcoLogic (today: Microchip Technology), and Active Silicon were among the biggest drivers, in 2008.
The goal was to develop a successor for the Camera Link standard for high-speed and data-rich vision related communication.
After a good reception, the standard writing consortium of industrial companies consisting of Adimec, Eqcologic, Active Silicon, AVAL DATA, NED, and Components Express was formed early 2009.
[2] By this time the Japan Industrial Imaging Association has adopted CoaXPress to mature it into an official standard after which the first draft version 1.0 was presented in December 2010.
[9][10][11][12] At least two companies develop CoaXPress-compatible driver and equalizer devices: Microchip Technology (through its acquisition of EqcoLogic) and Macom.
