A method and system for synchronizing a reference signal and an output signal produced by an electrical circuit, the electrical circuit comprising an analog portion and a digital portion, is disclosed. The method comprises the steps of utilizing the digital portion to produce a phase-adjusted signal and utilizing the analog portion to produce an output signal in substantially the same phase as the phase-adjusted signal. Through the use of the method and system in accordance with the present invention, the large bi-direction shift register of conventional hybrid DLLs is no longer necessary and high speed DLLs will be capable of providing high resolution deskewed clocks in a shorter amount of time. The use of the present invention also facilitates the coverage of a wider range of clock frequencies.
