High Speed Digital (HSD) transmit (Tx) and receive (Rx) circuits are modelled as SerDes systems using a channel simulator. Many channel simulators model S-parameter based channels with impulse responses with excessive high frequency aliasing.
This paper first gives an overview of high frequency aliasing issues in context with industry standards compliance testing, SerDes systems examples without and with the proposed anti-aliasing algorithm (AAA), and then the AAA is discussed.
