Abstract:
    The invention relates to a method for recovering clock and relative device, wherein it uses digit filter with full hardware logic in de-projection clock recover circuit; it uses point method to make FIR filter smoothly output cut time slit; it uses analogue phase-lock loop to recover the client clock, improves the vibration property when recovers clock. The invention can recover clock with low vibration, to improve bandwidth and stability of whole phase-lock loop, with low cost.
