摘要
针对高精度智能仪器仪表及传感器领域中数据高速传输的要求,设计了基于Aurora协议的光纤高速串行传输系统。利用Virtex-6 FPGA生成Aurora IP核,采用AD9516时钟芯片通过编程实现误差±100 ppm的时钟输出。最后通过SFP(small form-factor pluggable)光纤通信模块将数据由电信号转换为光信号,进行光纤高速传输,有效地提高了数据的传输速率。经实验仿真分析验证,所设计的多通道光纤高速传输系统传输速率高,性能稳定。
In order to meet the requirements of data high-speed transmission in high accuracy intelligent instrumentation and sensors fields,the fiber-optical high-speed serial transmission system based on Aurora protocol was designed.Virtex-6 FPGA was adapted to generate Aurora IP core, and clock chip AD9516 was used to output a clock with error ±100ppm by programming con- trol.Finally the SFP（ Small Form-Factor Pluggable）fiber-optic communication module was used for data conversion from electrical signal into optical signal, and optical signal can be transmitted over fiber-optical, so that data transmission speed was improved ef- fectively.The simulation experiments show that the designed multi-channel fiber-optic high-speed transmission system has high transmission speed and stable performance.
