Have you ever wondered about those signaling references? LVTTL, SSTTL_10, CML, PECL, etc. etc. I found a good reference here: www.idt.com/products/getDoc.cfm?docID=9841 It not only goes through the specifications for voltages, currents, etc. but also shows a little about the topologies and what technology niche that each serves. A good thing to keep on your desktop.
As it so happens, I worked for IDT back in the 90's when I was living in Salinas, CA. They always did a good job with their app notes.

Someplace I visit for now. In a few years I won't be doing it anymore.
