一种LVDS-光纤接口转换器的设计与实现

摘要

针对目前多数基于SFP光纤接口的高速传感器存储测试设备无法与频谱分析仪直接通信的现状,设计了一种基于FP GA的LVDS-光纤接口转换器.通过FP GA编程实现LVDS接口数据包和光纤接口数据包编码转换,利用DDR3对数据进行乒乓操作达到高速缓存目的,实现了频谱分析仪与高速存储测试设备间双工通信.经长时间实际测试没有出现误码,表明该转换器设计合理高效.%In view of the fact that most of the high-speed storage testing devices on sensors based on the SFP optical fiber in-terface can't communicate directly with the spectrum analyzer at present,a kind of LVDS-fiber interface converter based on FPGA was designed.The packet encoding conversion between LVDS interface and optical interface was realized by FPGA programming, and the data was Ping-Ponged by DDR3 to achieve the purpose of caching,which realized the duplex communication between the spectrum analyzer and the high-speed memory test equipment.After a long time test,there is not error code,indicating that the converter design reasonable and efficient.At present.
