Method and apparatus for synchronizing a control signal

A method of synchronizing a control signal with a first clock signal, the control signal having a phase relationship with a second clock signal, comprising the steps of:

• generating a plurality of intermediate clock signals using the first clock signal, a first one of said plurality of intermediate clock signals lagging the first clock signal, each successive one of said plurality of intermediate clock signals lagging a preceding one of said plurality of intermediate clock signals, and a last one of said each successive one of said plurality of intermediate clock signals serving as the second clock signal;
• and
• synchronizing the control signal with said plurality of intermediate clock signals to incrementally shift the phase of said control signal with said plurality of intermediate clock signals until the phase of said control signal corresponds to the phase of the first clock signal.

An apparatus for synchronizing a control signal with a first clock signal, the control signal having a phase relationship with a second clock signal, comprising:

• a clock generation means for generating a plurality of intermediate clock signals using the first clock signal, a first one of said plurality of intermediate clock signals lagging the first clock signal, each successive one of said plurality of intermediate clock signals lagging a preceding one of said plurality of intermediate clock signals, and a last one of said each successive one of said plurality of intermediate clock signals serving as the second clock signal;
• and
• a plurality of synchronization means for synchronizing the control signal with each one of said plurality of intermediate signals in a successive manner by proceeding from said last one of said each successive one of said plurality of intermediate clock signals to said first one of said plurality of intermediate clock signals to incrementally shift the phase of said control signal until the phase of said control signal corresponds to the phase of the first clock signal.
