Understanding Crosstalk for Signal Integrity Applications

摘要

Although crosstalk has been around for a long time, there's a growing interest in crosstalk as data-rates continue to increase and ICs/PCBs continue to shrink. This white paper provides an introduction to crosstalk with a specific focus on signal integrity applications offering guidelines of what to watch out for when measuring crosstalk.Using a simple simulation we will show why crosstalk is becoming so important in high-speed digital communication and why system level tools such as bit error rate testers and oscilloscopes are not ideal for pinpointing crosstalk issues and certainly not for troubleshooting.
