Loop filter: 通常是low pass的filter,用来稳定反馈系统和平稳控制信号。 VCO: 由电压控制的振荡器,它的输出频率可以看做是输入电压的函数。 这里需要用到一点自控的知识,现在我们来看一下经过拉普拉斯变换后的系统: 在Fig.2中,我们采用频域的角度来看整个反馈系统,输入和反馈信号变为相位,Loop Filter和VCO的传送函...
PLL主要模块: Phase Detector 类似EA, 放大 data in和dclock的 time difference. 送到 Loop filter. 经过Voltage-controlled oscillator (VCO). 这里有环路稳定性考量. DPLL不稳定的标准是the edge of output is not synchronized with the data, 即 not locked. The Phase Detector Phase Detector (PD) 分为 ...

He is currently applications manager of the Microwave Frequency Generation Group, which focuses mainly on phase-locked loop (PLL) and voltage controlled oscillator (VCO) products. When not spending time at work or with his young family, Ian enjoys photography and the theater (both on- and off-...
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 ...
A Phase-Locked Oscillator (PLO) is an electronic device designed to generate a stable and precise output frequency by locking the phase of its internal oscillator to a reference signal. The PLO uses a feedback control system called a Phase-Locked Loop (PLL) to synchronize the output signal of...
Digital Phase Locked Loop Model a digital phase locked loop using the Mixed-Signal Blockset™. In a digital phase locked loop, phase detection is performed by a time to digital converter (TDC), loop filtering is performed by a digital filter, and the oscillator is a digitally controlled osci...
