Comparison of Synchronization Techniques Under Distorted Grid Conditions
IEEE Access, 2019 In grid-connected power converter applications, the phase-locked loop (PLL) is probably the most widely used grid synchronization technique, owing to its simple implementation. However, in power grids some very common problems, such as voltage distortion,

Low-Jitter Clock Multiplication: a Comparioson between PLLs and DLLs [PDF]
, 2002 This paper shows that, for a given power budget, a practical phase-locked loop (PLL)-based clock multiplier generates less jitter than a delay-locked loop (DLL) equivalent. This is due to the fact that the delay cells in a PLL ring-oscillator can consume
