摘要
设计基于MCl45163P的智能锁相频率合成器,此系统是在经典频率锁相合成器电路的基础上,加入单片机控制环节,实现频率输出的自动控制、预置频率值、显示频率等功能。对系统的实现作了详细描述,最后对系统作了实验验证及分析。
In this paper,intelligence PLL frequency synthesizer based on MCl45163P is designed.The system,based on the classic phase-locked frequency synthesizer circuit,join the single-chip control link,to achieve automatic control of output frequency,preset frequencies and indicating features for the frequency.The realization of the system is described in detail.Finally,experimental verification and analyzed of the system are made.
