AN535 PhaseĆLocked 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.
