PLL (Phase Locked Loop): It is a phase-locked loop or a phase-locked loop, which is used to unify and integrate clock signals to make high-frequency devices work normally, such as memory access data. PLL is used for feedback technology in oscillators. For many electronic devices to work...
A working method of the PLL system is also provided, which can restrain input noise as well as phase noise of the second VOC in such a manner that noise of the PLL system is well restrained.doi:US20140176204 A1Fangping FanUS
A phase-locked loop (PLL) is an electronic circuit with a voltage or voltage-driven oscillator that constantly adjusts to match the frequency of an input signal. PLLs are used to generate, stabilize,modulate, demodulate, filter or recover a signal from a "noisy" communications channel where d...
In its most basic configuration, a phase-locked loop compares the phase of a reference signal (FREF) to the phase of an adjustable feedback signal (RFIN) F0, as seen in Figure 1. In Figure 2 there is a negative feedback control loop operating in the frequency domain. When the compariso...
Phase-locked loop (PLL)A phase-locked loop (PLL) is a feedback circuit designed to allow one circuit board to synchronize the phase of its on board clock with an external timing signal. PLL circuits operate by comparing the phase of an external signal to the phase of a clock signal ...

the paper introduces the phase - locked loop first , including its working theory , the design of the loop filter and noise. 本文首先介绍了锁相环。对它的工作原理、环路滤波器的设计以及噪声理论进行了阐述。 www.ichacha.net 10. The clock and data signal are synchronized and recovered by the ph...
Phase Locked Loop(PLL)学习2 上次我们了解了symbol_timing PLL的一些知识,近期项目忙的差不多了,开始更新下传统PLL的一些内容。其实两者的本质都是比较接近的,只是针对不同的应用场景而已。symbol_timing PLL通过MM等TED(Timing Error detect)算法来判断时钟超前或者滞后,从而控制相位插值器来调整相位,达到相位跟踪的...
