Clock extraction
WebThe spectrum of an NRZ signal has zero energy at the clock frequency. Therefore, clock extraction for an NRZ signal is more complicated than that for RZ. Typically, to recover the clock from an NRZ data pattern, a narrowband filter has to select the frequency component at half data rate, which is the fundamental frequency of the NRZ signal. Webvisible in the behavior of the clock recovery circuit and covered by receiver sensitivity – Signal dependent phase deviation in the bit stream related to clock extraction circuit implementation • Effect that would add signal correlated Clock noise relative to incoming bit clock signal to the recovered receiver clock . Filtered by the PLL ...
