Abstract
Introducesthe principle of phase locked loop frequency synthesizer and analyzes the performance characteristics of PLLchip MC145156-2. Then presents an example that a phase locked loop frequency synthesizer is designed with PLL chip MC145156-2. The experimental results prove that the design is reasonable and practicable. The frequency stability of this system is better than 10~(-7).
