| Abstract: | Based on the DP interface standard,combined with the effects that system parameters of phase-locked loop circuit impact on the stabilized time and noise,how to select the system parameters values can studied.A group of parameter values with better performance is given,the set of parameters are provides stable current and voltage for the charge pump and voltage-controlled oscillator.The simulation is carried out with PLLsim software,which verifies that the datas is feasible and correct. |
