摘要
介绍了锁相环路频率合成器的基本原理,分析了集成锁相环芯片MC145156-2的工作特性,并给出了集成锁相环芯片MC145156-2的一个应用实例.测试结果证明了设计的合理性与实用性,系统频率稳定度优于10^(-7).
Introduces the principle of phase locked loop frequency synthesizer and analyzes the performance characteristics of PLL chip MC 145156-2. 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.
