基于信号完整性的板间互连设计

Design of Interconnection between Boards Based on Signal Integrity

在由现场可更换模块组成的电子设备中,board to board互连的信号完整性问题举足轻重。基于信号完整性,搭建互连链路,进行SRIO总线传输,速率10.3125 Gbps,经由两组连接器及20 inch的有损传输线,对信号质量指标进行核算,对全链路进行仿真验证。

In the electronic equipment composed of field replaceable modules,the signal integrity of board to board interconnection is very important.Based on the signal integrity,the interconnection link is built for sRIO bus transmission at the rate of 10.3125 gbps.The signal quality index is calculated through two groups of connectors and 20 Inch lossy transmission line,and the whole link is simulated and verified.
