Abstract :
With the help of real-time numerical simulation results, the acquisition properties of a second-order ZC1-DPLL are investigated. Besides confirming the sensitivity of the system dynamics to the initial values of the state variables, it predicts qualitatively the maximum possible frequency acquisition range (FAR) of the system, and obtains the values of the maximum FAR for systems with different design parameters. The effect of jitter on the loop dynamics has also been considered
