摘要
提出了VOR地面信标模仿仪对频率合成器的要求,介绍了集成锁相环芯片MC145152的工作特性,验证了基于MC145152的PLL频率合成器在VOR地面信标模仿仪中的设计与实现的有效性。测试结果证明设计的合理性与实用性,系统频率稳定度优于10-7。
frequency requirements for OVR Marker Simulator are presented. The principle of phase locked loop frequency synthesizer and the performance characteristics of PLL chip MC145152 are discussed. The validity of design and implementation of OVR Marker Simulator Frequency Synthesizer based on MC145152 is substantiated. The experimental results show that the design is reasonable and practicable. The frequency stability of this system is better than 10^-7.
