摘 要: 讨论了锁相式频率合成器的基本原理。设计了一种通用可编程锁相式频率合成器,介绍了其编程置数格式,提出了一种可提高程控分频器工作频率的电路设计方法,并给出了其模拟波形。该电路的最高合成频率为100MHz,最小频率间隔为100Hz,在工程上具有广泛的应用前景。 A universal programmable frequency synthesizer has been designed. The format of programming is described in detail. A design method to increase the operating frequency of the programmable frequency divider is presented, and its simulation results are given. A maximum synthesizing frequency of 100 MHz and a minimum step of 100 Hz have been achieved for the circuit, which can be widely used in engineering applications.
