摘要
数字锁相频率合成器是一种在通信、雷达等领域中得到广泛应用的器件。本文首先阐述了吞除脉冲式数字锁相环的基本原理,其次介绍了采用该技术的LMX1501芯片,最后对使用该芯片的PAET6系列甚高频通信电台中的频率合成器模块进行了深入分析。
Digital phase-locked frequency synthesizer is a widely used device in the fields of communication,radar and so on.This paper firstly describes the basic principle of swallowing pulse digital phase-locked loop.Secondly,the LMX1501 chip using this technology is introduced.Finally,the frequency synthesizer module in the PAE T6 series VHF communication radio using the LMX1501 chip is deeply analyzed.
