Abstract
The 10Gbps high-speed serial interface has been used in data transmission widely. As the bandwidth demanding for high-speed communication network sharply increases, it is increasingly important to investigate the interconnection of high-speed serial interface. In this paper, the SFP+ interface signal integrity (SI) were analyzed with EM simulation and the lab measurement. The 2.5D and 3D modeling methodologies were introduced for the interest transmission line in the frequency domain. We measured its differential mode (DM) reflection and transmission coefficients, subsequently observed the variation of DM impedance and analyzed the causes of impedance discontinuity by the utilization of TDR measurement, and finally put forward several methods to improve the SI. It is notable that the simulation results of the 2.5D and 3D model are almost identical by comparison, which means that 2.5D modeling methodologies also can achieve high accuracy around 10Ghz. Additionally, we optimized the SI simulation results by varying the output voltage and pre-emphasis parameters. Finally, the SFP+ compliance test shows the simulation has good agreement with lab measurement in the time domain.
