光通信系统时钟提取单元的抖动特性

Jitter Performance of Timing Recovery Unit of Optical Communication Systems

本文由光通信系统中定时抖动功率谱的一般表达式,分析比较了平方律(SL)和线性整流(LR)两种不同非线性电路(NLC)的抖动特性。

Two groups of expressions about jitter spectra are deducted, which are relative to two nonlinear circuits (NLCs), square-law (SL) and linear-rectifier (LR), in timing unit of optical communication systems. Their jitter properties are compared with typical parameter values.
