摘　　要：针对LVDS接口,研究并实现了一种基于FPGA的LVDS过采样技术,重点对LVDS过采样技术中系统组成、ISERDESE2、时钟采样、数据恢复单元、时钟同步状态机等关键技术进行了描述,并基于Xilinx FPGA进行了验证,传输速率达到了1.25Gbps。文章的研究为基于FPGA实现系统之间的高速互连具有一定的工程参考价值。Aiming at LVDS interface this paper research and implement a kind of asynchronous LVDS oversampling technology based on FPGA. The paper describes the key technologies in the LVDS oversampling, including system composition, ISERDESE2, clock sampling, data recovery unit and clock align machine in detail. And it validates the validity of the system based on Xilinx FPGA, the transmission speed achieved 1.25Gbps. This paper is of certain engineering reference value for high speed interconnection between systems based on FPGA.
