1.5 Summary
In this chapter, we've introduced the basic concepts of high-speed serial transmission systems: clock architectures, line coding, and differential electrical signaling with preemphasis or receiver equalization.
The remainder of this book describes how we can characterize such a system, either as a whole or individually for its components. Transmitter tests verify the electrical performance of the signal before it enters the channel, while receiver tests verify that the worst-case realistic signals can be understood by the receiver. Channel tests finally determine the quality of the transmission medium.
