  • Method and system for clock deskewing using a continuously calibrated delay element in a phase-locked loop
    Patent number: 6806750
    Abstract: A method for clock deskewing using a continuously calibrated delay element in a phase-locked loop is provided that includes receiving a feedback signal. A skew select signal is received. The feedback signal is delayed based on the skew select signal to generate a delay output signal. The delay output signal is provided to a phase detector. An external clock signal and the delay output signal are received at the phase detector. A phase detector signal is generated based on the external clock signal and the delay output signal. A skewed clock signal and the feedback signal are generated based on the phase detector signal.
