Common mode filters

Introduction

In our connected world, data exchange very fast and their content is shown in a large screen

with high-definition capabilities. These features include high-speed serial links, working in

different modes and increasing data rate. However, fast transition times and long lines may

induce radiations due to common mode noise. In order to avoid these issues, the most

device and its benefits are described.
