摘要/Abstract

摘要：

从信道响应函数出发，推导了高速串行通信中计算数据相关性抖动的一般公式，结合mBnB编码规则，提出了以单位脉冲响应的幅度作为权重的优先迭代算法，求得使数据相关性抖动取得极值的mBnB编码序列，进而计算数据相关性抖动峰峰值．利用实测得到的信道参数验证了该算法，相比于发送大量随机mBnB编码码流来遍历搜索数据相关性抖动极值的方法，该方法计算简单，且误差小，能够快速准确地得到mBnB编码码流的数据相关性抖动的峰峰值，并可据此评估不同mBnB编码的抖动性能．

Abstract:

A formula for data dependent jitter (DDJ) is derived from the pulse response function of the high speed serial link. Based on the formula and mBnB encoding schemes, an iterative algorithm for finding the input bits which has the maximum or minimum of DDJ is presented and the peak-to-peak value of DDJ is calculated. Compared to the ordinary method of using lots of random mBnB coded bits to search for the peak-to-peak value of DDJ, this method is more accurate and with less computational complexity. The result can be used to evaluate the jitter performance of different mBnB coding schemes.

Key words: data dependent jitter, mBnB coding, 8B10B coding, 4B5B coding, pulse response
