CoaXPress Evolution: Future-Proof High-Speed Imaging Interface
CoaXPress standard was developed over 9 years ago to overcome the limitations of Camera Link, including its limited bandwidth (maximum 850 MB/s) and short, bulky cables. Even after winning the Vision Award in 2009 and gaining technical advantages over other high-speed imaging interface standards, CoaXPress faced skepticism as a risky option. At the time, there was only one source for the transceiver/receiver chip from EqcoLogic (now part of MicroChip), and it took several years before JIIA (and later G3) provided backing.
In 2016, CoaXPress emerged as the least risky choice for future systems. It continues to offer the fastest speeds with power and camera control through long, flexible cables. Plans exist to achieve even faster speeds without sacrificing cable length, but its low-risk status extends beyond just technology.
Is it Possible to Future-Proof?
For image system designers upgrading to new technologies, they seek clarity on second and third-generation developments. Nobody wants to make a change now only to face costly system redesigns when data rates double in the future. Many customers currently use 6.25 Gbps per cable for data rates of 12 Megapixels at 187 fps (using four cables). In five years, typical data rates are expected to double, and CoaXPress’s next generation will support this with 12.5 Gbps per cable.
The standard also requires careful management to ensure upgrades remain seamless. Unlike other emerging interfaces, which often have limited frame grabbers or incompatible connectors, CoaXPress avoids these issues. For example, USB 3.1 increases data rates to 10 Gbps per cable but restricts cable length to just one meter.
CoaXPress has a solid roadmap and strong support from multiple companies, encouraging component suppliers to develop products aligned with its specifications. In contrast, technologies like 10 GigE face uncertain future standards, limiting product availability. CoaXPress benefits from input from over 30 companies, ensuring broad application needs are met while maintaining compatibility through controlled development.
What’s Next
With widespread adoption in the US, CoaXPress is expected to gain traction globally. Industries like automotive and broadcasting may also adopt it as a forward-looking solution.
