Abstract
A method and apparatus is provided for performing a filter control of a delay lock loop circuit. A coarse delay and/or a fine delay are implemented upon a reference signal based upon a phase shift between the reference signal and a feedback signal. A synchronized output signal is generated based upon the coarse delay and the fine delay. The apparatus of the present invention includes a delay lock loop to provide an output signal based upon a phase difference between a reference signal and a feedback signal. The delay lock loop comprises a filter to provide a filter response to the phase difference. The filter response is capable of providing a coarse delay and/or a fine delay.
