PURPOSE: A phase locked detection circuit for PLL(Phase Locked Loop) is provided to determine correctly a phase locked state by improving a structure of a phase locked detection circuit for PLL. CONSTITUTION: An XOR gate(31) performs a logical operation for a reference signal and a PLL output...
在Fig.1.中显示了一个基础的PLL结构框图,它是一个简单的反馈系统。这里为了简化起见,省略了分频器。Fin(t)是从外界输入的参考频率信号,Ffeedback(t)是从VCO反馈回来的频率信号,而Fout(t)则是最终输出的频率。这个反馈系统主要包含了以下三个部分: Phase detector: 检测input frequency和feedback frequency的相位...
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 ...
