JITTER SUPPRESSION IN TYPE I DELAY-LOCKED LOOPS

摘要

In one embodiment, a delay-locked loop (DLL) for synchronizing a phase of a periodic digital output signal with a phase of a periodic digital input signal includes a deskew element responsive to the periodic digital input signal to the DLL and the periodic digital output signal from the DLL for suppressing jitter in the periodic digital output signal by synchronizing transitions in the periodic digital output signal with transitions in the periodic digital input signal and generating a final jitter- suppressed periodic digital output signal.
