Phase-Locked Loop Design Fundamentals

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 purpose of this application note is to provide the electronic system designer with the necessary tools to design and evaluate Phase-Locked Loops (PLL) configured with integrated circuits. The majority of all PLL design problems can be approached using the Laplace Transform technique.
