Solving signal integrity problem of LVDS buffer with SigXplorer

摘要

Signal integrity(SI) problems for LVDS(Low Voltage Differential signaling) buffer is the bottleneck in receiver circuits design. This paper presents a novel simulation method to solve the real SI problem. Firstly, the SI problem which has been tested in the receiver equipment was reproduced by the software of SigXplorer. Then, the circuit was improved, and a stable signal was received by LVDS buffer in simulation. Finally, the method was proved to be correct by test. Some design experiences are summarized, which could be operated expediently and put into excellent application.
