Abstract

With the continuous development of sensor technology, the interface throughput has become a bottleneck for sensor performance. The emergence of CoaXPress2.0 protocol facilitates optimal sensor performance in cameras. This study utilizes Microchip’s FPGA and PHY chips to construct a set of CoaXPress2.0 protocol communication equipment, integrated with Sony IMX455 sensor to achieve 62.39MP image at 17.9fps output, reaching the theoretical maximum frame rate of the sensor. It is three times the frame rate of USB3.0. With the continuous development of sensor technology, the throughput of the interface limits the performance of the sensor, and the emergence of CoaXPress2.0 protocol helps the camera to play the best performance of the sensor. The experimental equipment achieved a maximum communication rate of 12.5Gbps per cable under CoaXPress2.0 protocol, with a single cable bandwidth reaching 10.9Gbps for image data. Additionally, a method is proposed to configure sensor registers using soft check, eliminating the limitation of requiring a specific host computer to open the camera, thereby enhancing the versatility of industrial cameras.
