The Delay-Locked Loop - University of California, Los Angeles
www.seas.ucla.eduDelay-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
