Differential Signaling

This chapter explores the essential elements of differential signaling. It illustrates the many benefits of differential operation and lays out the conditions under which those benefits may be obtained. It also gives some practical advice about how to best manage differential connections.

I'll begin with a detailed, start-from-the-basics look at single-ended signaling architectures, then extend the analysis to cover differential signaling . The point of this presentation is to break down differential signaling into its component parts to show how precisely the various benefits are obtained.
