This chapter introduces fundamental concepts for understanding phase, phase noise, and jitter, as well as their effect on the PLL. A review of fundamental PLL and phase noise concepts shows how VCO jitter is shaped by PLL loop dynamics to determine system-level jitter. After a brief introduction to jitter measurement techniques, several different system-level jitter and phase noise measures are speciffed which will be related by a mathematical framework to be described in Chapter 5.
