CoaXPress® technology is an open and royalty-free asymmetric, high-speed, point-to-point open serial communication standard for high-performance machine vision, industrial inspection and traffic monitoring systems. It provides a state-of-the-art method for connecting high-performance, high-resolution cameras to high-speed capture cards – also known as frame grabbers – via standard, off-the-shelf 75Ω coaxial cables.
PolarFire® FPGAs and CoaXPress® Technology
We offer a ready-to-use reference design for quick prototyping of your CoaXPress technology-based design using PolarFire FPGAs. This solution is well suited for creating next-generation embedded vision platforms that integrate Artificial Intelligence and Machine Learning.

These applications typically require multiple 4K channels for higher resolution, more thermal head room on the edge, low power consumption, small form factors and portable designs.
Target Applications:
- Industrial machine vision
- Medical endoscopes
- Robotic vision
- Automotive
PolarFire® FPGAs and CoaXPress® Reference Design
CoaXPress FMC Daughter Card
The CoaXPress boards support a 12.5G CoaXPress PHY and include ready to use reference designs for quick prototyping. Microchip’s CoaXPress FMC daughter card is the hardware evaluation platform for evaluating and testing the CoaXPress protocol. The daughter card works with the PolarFire Video Kit which features the PolarFire FPGA device. This kit needs to be purchased separately.
