摘　　要：简要介绍甚短距离光传输系统,分析各种帧对齐电路的性能,提出一种针对同步数字体系(SDH)高速数据的全新的基于二分查找的并行帧对齐电路。选用Altera公司StratixEP1S25F780C5现场可编程器件芯片下载验证。仿真和测试表明,速度和芯片面积均较以往方法有较大提高。This paper gave a brief introduction to the very short reach optical transmission system, analysed features of current word alignment circuits, and proposed a novel parallel binary search word alignment circit specifically for SDH systems. The logic function are simulated and verified by using Stratix FPGA EP1S25F780C5 from Altera corporation.
