基于FPGA的PLL频率合成器
PLL frequency synthesizer based on FPGA
【摘要】 应用FPGA,采用PLL频率合成技术,结合教学实验平台的需要,设计出了一个整数/半整数频率合成器,输出范围为1kHz~999.5kHz,步进频率可达到0.5kHz。与以前的教学实验装置相比,系统在性能指标、直观性等方面都有所提高,不仅可以用于教学实验,还可以用作频率源、频率计。
【Abstract】 Using the phase-locked loop frequency(PLL)synthesis and FPGA technology,this paper has designed an integer/half-integer frequency synthesizer,which can export frequency from 1 kHz to 999.5 kHz at step frequency of 0.5kHz,taking the need of teaching demonstration into consideration.Compared with the former PLL installation in the teaching laboratory,this system improves in aspects of capability indexes and intuitive demonstration and so on.It can be used not only in the teaching experiments,also can serve as the frequency source and frequency meter.
