MT-086: Fundamentals of Phase Locked Loops (PLLs)

www.analog.com

A phase-locked loop is a feedback system combining a voltage controlled oscillator (VCO) and a ... counter element to bring the very high input frequency down to a range at which standard CMOS will operate. This counter, called a prescaler, is shown in Figure 3B.

Delay-locked loops (DLLs) can be considered as feedback circuits that phase lock an output to an input without the use of an oscillator. In some applications, DLLs are neces-sary or preferable over phase-locked loops (PLLs), with their advantages including lower sensitivity to supply noise and lower phase noise. This
