Phase-locked loop has two characteristics of the narrowband and broadband, and has strong processing capacity of doping the noise signal. Begin with the phase~locked loop bandwidth and phase margin, its design methods and processes are described. Then based on the design of analog phase-locked loop, the digital realization of the method was given.
