摘　　要：以cyclone FPGA器件为核心,设计数据交换机。文中结合交换机的设计,详细描述了cyclone器件中LVDS接口、锁相环PLL、片内M4K RAM模块、芯片配置的应用方法和技巧,给出了软件设计的思想,并研制了数据下载线。经实际测试和运行,交换机的各项性能指标达到原设计要求,并具有高可靠性和高性价比。The data switch using cyclone FPGA device as the core is designed in the paper. Combining the design of switch,the application and technique in Cyclone LVDS I/O interface,PLL, M4K RAM blocks are discussed detailedly. The thoughts of software design is given, and circuit of download cable is developed. Through testing and running actually ,the performance is up to the original target, and it has the advantage of high reliability and cost performance.
