摘要
描述了一种光纤通信系统中基于FPGA实现的全数字通信系统同步电路的原理,在MAX+PLUSⅡ环境下结合原理图和VHDL语言进行了综合、仿真和配置,该电路实现了同步电路的全数字化。测试结果表明,该设计方法能比较准确地恢复同步信号。
The principle of a digital communication synchronism based on FPGA in optical communication is described. Then using MAX ＋ PLUS Ⅱ software, colligation, simulation and synthesis are realized on the basis of the graphic editor and text editor. The design digitizes the synchronism circuit. Test results show that the design method restores synchronous signals more accurately.
