The ADIsimPLL design tool is a comprehensive and easy-to-use PLL synthesizer design and simulation tool. All key non-linear effects that can impact PLL performance can be simulated, including phase noise, Fractional-N spurs, and anti-backlash pulse.
在频率合成（FS, Frequency Synthesis）领域中，常用的频率合成技术有模拟锁相环、数字锁相环、小数分频锁相环（fractional-N PLL Synthesis）等，直接数字合成(Direct Digital Synthesis－DDS)是近年来新的FS技术。单片集成的DDS产品是一种可代替锁相环的快速频率合成器件。DDS是产生高精度、快速变换频率、输出波形失真小的优先选用技术。DDS以稳定度高的参考时钟为参考源，通过精密的相位累加器和数字信号处理，通过高速D/A变换器产生所
