随着电子产品的系统时钟不断变高,数据传输速率越来越快,印刷电路板的布线结构等就会产生更多的问题,这就产生了电磁兼容(EMC)以及信号完整性的问题,文章借助信号完整性分析工具Hyper Lynx仿真软件,对基于LT86101及LT86102的KVM延长器硬件系统进行信号完整性分析和仿真。对此系统的端接,串扰等性能指标做信号完整性的仿真分析,并通过系统后仿与实测结果对比论证信号完整性的效果,同时提高产品的电磁兼容性能。
As the system clocks of electronic products continue to rise and data transfer rates get faster and faster, more problems arise with the printed circuit board wiring structure and the like, which results in problems of electromagnetic compatibility (EMC) and signal integrity, The paper analyzes and simulates the signal integrity of KVM extender hardware system based on LT86101 and LT86102 with Hyper Lynx simulation software. The signal integrity of the system performance indicators such as termination, crosstalk and other indicators of the simulation analysis, and through the system simulation and test results compared to demonstrate the effect of signal integrity, while improving the product’s electromagnetic compatibility.
