锁相环设计MOTOROLA SEMICONDUCTOR APPLICATION NOTE Order this document by AN535/D AN535 PhaseLocked Loop Design Fundamentals Prepared by: Garth Nash Applications Engineering ABSTRACT The fundamental design concepts for phase-locked loops implemented with integrated circuits are outlined. The necessary equations required to evaluate the basic loop performance are given in conjunction with a brief design example. The parameters in Figure 1 are defined and will be used throughout the text. θi(s) + ……
