This paper first gives an overview of high frequency aliasing issues in context with industry standard compliance testing, then discusses the anti-aliasing algorithm. Read on. 

In this paper, John Baprawski gives an overview of modeling SerDes systems in a channel simulator, introduces the zero-cost tools available at SerDesDesign.com, and gives an example of simulating a SerDes system with Tx and Rx IBIS-AMI models – all to bring the SI engineer a low cost path for modeling and simulating SerDes systems.

In this article, John Baprawski reviews various issues when using S-parameter files to represent the channel in a SerDes system channel simulator. Stepping through several detailed examples, he demonstrates how paying close attention to the quality of the S-parameters allows you to have confidence in the derived SerDes design eye diagrams and other analysis methods.
