摘　　要：叙述了由单片机、定时计数器 82 5 3-5及单片集成锁相环路组成的可程控频率合成技术 ,而标频可经单片机设定预置值给定时器T1 而形成 ,并经锁相环路产生各种离散的频率输出。This paper discusses the programmable-controlled frequency synthesis consists of Single-chip, timing counter and please-locked loop. The standarded frequency is formed by the Single-chip computer setting an setting value to timing counter, and the phase-locked loop produces diffrents frequencies discreted for output.
