DVI接口的TMDS链路通讯中抖动问题研究

DVI interface study In Jitter question of TMDS link communication

DVI接口的数据传输信号频率已接近微波波段,在如此高速串行数据通讯中会表现出典型的抖动效应。DVI接口电路设计中抖动是DVI接口的TMDS链路通讯的最为关心的问题之一,本文从TMDS连路结构及时钟同步与数据恢复两个方面对链路的抖动问题进行研究,并给出一些解决方案。

Signal frequency in data transmissio of DIV interface have already been close to microware band,and will demonstrate the typical great jitter effect in the data communication of so high frequency.In the design of DVI interface cireuit,jitter is one of the most cared problems on TMDS link communication of DVt interface.According to the theary of TMDS link formation,clock synchronism,and data recovery,the paper works on the study of link jitter problem and points out some solutions to work out.
