基于FPGA的SFI-5协议信号源的设计与实现

Design and implementation of SFI-5 signal source based on FPGA

为了便于40G高速光纤信号数据采集系统的仿真和调试,提出了一种基于高速光电转换模块接口协议SFI-5信号源的FPGA实现方法。该方法采用64位的并行伪随机码作为信号源的输入,按照协议要求同步输出16个16位的数据通道和1个16位对齐通道。经40G高速光纤信号数据采集系统的测试,符合采集系统发送模块性能要求。

In order to simplify the simulation and the debug of the 40Gb/s high-speed optical signal data ac- quisition system, this paper comes up with a solution of signal-source based on SFI-5 on the platform of FP- GA. The method applies 64-bit-width parallel pseudo-random code as the signal-source＇s input, and in accor- dance with SFI-5 sync outputs 16 16-bit-width data lanes and a 16-bit-width deskew lane. By the test of 40Gb/s high-speed optical signal data acquisition system, it satisfies the demand of transmit system.
