A novel all optical scheme for extracting clock pulses with basic frequency from the receiving non uniform OTDM optical signal is proposed.
提出从接收到的光信号脉冲串中提取光基频时钟的方案。
A phase frequency detector compares a reference clock signal to a feedback clock signal to generate pulses in one or more output signals.
相位频率检测器比较基准时钟信号和反馈时钟信号从而在一个或更多个输出信号中生成脉冲。
When the phase and frequency of the reference and feedback clock signals are the same, the PLL is in lock mode, and the PFD does not generate pulses in its output signals.
当基准和反馈时钟信号的相位和频率相同时,PLL处于锁定模式,且PFD输出信号中不生成脉冲。
