基于FPGA的高速串行IO研究

Research on high-speed serial IO based on FPGA

针对高速串行IO接口中的GTX收发器,通过Ibert测试工具对预加重、均衡器、采样位置等参数进行优化,并且充分利用comma字符对齐、时钟修正、8 B/10 B编码技术,有效降低高速传输过程中的误码率,实现GTX的高效稳定通信。

For GTX transceiver in the high-speed serial IO interface,the testing tool Ibert is used to optimize the parameters such as pre-emphasis,equalizer and sampling position.The comma alignment,clock correction and 8B/10B encoding technologies are adopted to reduce the error rate and realize the stable communication during the GTX high-speed transmission.
