This paper present a simple model to show the mechanisms that produce digital frequency dividers' aliasing effects.And we also get a relationship to determine the amplitude and location of the spurs and PM noise in the output frequency. With its aid, we can calculate the spurs and PM noise in the output signal of the PLL more accurately.
