The latest ultra-resolution industrial image sensors are delivering impressive performance, particularly in terms of pixel throughput. We’re seeing capabilities like 25 megapixels at 72 frames per second, traditionally transferred via Camera Link, now increasingly utilizing CoaXPress (CXP) interfaces. This shift unlocks new possibilities for high-speed data acquisition.

Region of Interest (ROI) and Frame Rate Optimization

A key benefit of CXP is the ability to leverage Region of Interest (ROI) functionality. This allows you to define a smaller area within the image sensor to capture, significantly reducing the data stream while maintaining high frame rates. For example, the Q-12A180/CXP camera, featuring a CMOSIS CMV12000 global shutter sensor, achieves 187 frames per second with a 4096 x 3072 pixel resolution. This translates to 2.3 GPixel/s. By utilizing ROI, frame rates can be dramatically increased, even at lower resolutions. The theoretical maximum frame rate for a 100x100 pixel ROI is 235,000 fps, though the actual achieved frame rate is 4,738 fps due to sensor design.

Introducing the Sapphire 25 Megapixel CXP Camera

Our Sapphire 25 megapixel CXP camera, utilizing an ON Semiconductor Vita25k global shutter sensor, delivers 72 full frames per second at 5120 x 5120 pixels – a rate of 1.9 GPixel/s. Like the Q-12A180/CXP, this camera utilizes the CoaXPress V1.1 Quad interface (4 x CXP-6).

CoaXPress V1.1 Quad: High-Speed Data Transfer

Both the Q-12A180/CXP and Sapphire 25 megapixel CXP cameras are built around the CoaXPress V1.1 Quad interface, offering a peak transfer rate of 2 Gigapixels/s. This interface utilizes four CXP-6 connections, enabling data transmission up to 25 Gbits/s (4 x 6.25 Gbits/s). Furthermore, the low power consumption of these cameras allows for operation over a single CoaXPress cable, supporting cable lengths of over 30 meters without signal repeaters or quality degradation.

Key Benefits

  • High Throughput: Achieve frame rates of up to 2 Gigapixels/second.
  • Low Power Consumption: Operate with a single CoaXPress cable.
  • Compact Design: Fanless architecture for easy integration.
  • Reliable Performance: Ideal for demanding in-line optical metrology systems.
