Interfaces and signals are not really eye diagrams. An Eye diagram is just something what will help you to find out how good a signal is - if it meets mask requirements.
You will learn about interfaces as you will be using them - I would recommend to buy some cheap boards and connect them. Then you can play with different kind of interfaces and signals e.g. transfer data between boards, connect a scope, try to decode the signal etc. Often you learn when the communication doesn't work and you need to figure out why.
And, of course, you can find some videos on youtube, but for deep understanding the best is to do some debugging and problem fixing.
