Signal integrity of electronic boards
Intégrité de signal et compatibilité électromagnétique (CEM) des cartes électroniques

Signal Integrity (SI) is defined as an engineering discipline whose objective is to guarantee that on the board designed :

• signals are transmitted and received correctly with controlled propagation times;

• the propagation of these signals does not interfere with other signals or with the signals themselves;

• the amplitude (current, voltage) of the signals does not exceed the limits guaranteed by the component manufacturers.

With this in mind, SI's actions are aimed at :

• eliminates unwanted signal reflections and minimizes losses;

• reduction of crosstalk or coupling between signals ;

• minimization of reference voltage instabilities....
