CoaXPress represents a significant leap forward in digital interface standards for imaging systems. This technology enables high-speed data transmission from devices like cameras to hosts such as frame grabbers within PCs, delivering speeds up to 6.25 Gbps over a single coaxial cable. Its advantages extend beyond mere speed, enhancing overall system performance in multiple ways:

Key Benefits of CoaXPress

1. Higher Resolution at Faster Frame Rates

Modern CMOS global shutter sensors (e.g., the CMV12000) achieve impressive resolutions and frame rates. For instance, a 12-megapixel sensor can capture images at 4096 × 3072 pixels with up to 187 frames per second (fps). CoaXPress supports this performance using just four cables. Similarly, 25-megapixel cameras can reach speeds of 80 fps via CoaXPress compared to about 30 fps over Camera Link.

2. Increased Bit Depth for Better Accuracy

CoaXPress’s high bandwidth allows systems to maintain higher bit depths (e.g., 10 bits) without sacrificing frame speed, improving measurement accuracy and dynamic range while keeping throughput efficient.

3. Reduced Power Consumption

Compared to Camera Link at similar speeds, CoaXPress consumes significantly less power—next-generation designs can achieve full frame rates with as little as 8W (fanless). However, implementation matters: some ultra-high-resolution cameras still require substantial power (up to 28W).

4. Future-Proof Scalability

CoaXPress’s roadmap ensures compatibility with evolving demands. The next generation will support up to 12.5 Gbps per cable, enabling seamless upgrades for system designers over the coming decade.

5. Fewer Cables and Simpler Systems

Unlike other interfaces requiring multiple cables for separate functions (video, control, power), CoaXPress consolidates everything into one coaxial cable, reducing complexity and costs. This simplicity is invaluable in applications like machine vision, medical imaging, and automotive systems where long or flexible cabling is essential.

6. Longer Cable Lengths

Extended cable lengths (e.g., meters) support flexibility in system design—ideal for moving parts, security monitoring in vehicles, or innovative uses like endoscopes.

7. Multi-Camera Simplification

CoaXPress excels in multi-camera setups. A single frame grabber can manage multiple high-resolution cameras with absolute synchronization and minimal cabling overhead. This scalability supports diverse applications from industrial inspection to advanced research systems.

Conclusion

CoaXPress combines speed, efficiency, and flexibility to transform imaging system design. By addressing bandwidth limitations, reducing power needs, and simplifying complex setups—whether for single high-resolution cameras or multi-camera architectures—it empowers engineers to build more capable, reliable, and cost-effective solutions for demanding applications worldwide.
