基于TC9181的数字锁相频率合成器的设计

Design of Digital Phase locked Frequency Synthesize Based on TC9181

文章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TC9181的工作特性,给出了基于集成锁相环芯片TC9181的“吞除脉冲”式串行数字锁相频率合成器设计方法,为高频频率合成器的设计提供了一个较好的思路。

This paper introduces the basic principle of phase locked frequency synthesize,analyses the charactics of integrated phase locked chip TC9181, obtains the design method of “swallow counter” serial digital phase locked frequency synthesizer based on TC9181, and obtains the good idea of the design of the digital phase locked frequency synthesizer.
