An Introduction to Preemphasis and Equalization in Maxim GMSL SerDes Devices

By: Caglar Yilmazer

Abstract: Transmit preemphasis and receive equalization can allow serializer/deserializer (SerDes) devices to operate over inexpensive cables or over extended distances. This application note describes how signals are degraded over cables and how to compensate for that degradation. Additionally, this document explains how to achieve a robust link with Maxim gigabit multimedia serial link (GMSL) products when using lossy cables. The article also provides an overview on line equalization.
