Abstract
An apparatus which generates a clock signal includes a first phase mixer which generates an initial clock signal based on a first set of reference clocks and a buffer which adds a first predetermined delay to the initial clock signal to produce a first clock signal. A phase detection circuit detects a difference in phase between the first clock signal and a master clock signal, and a control circuit selects a second set of reference clocks based on the difference in phase and a second predetermined delay. A second phase mixer generates an output clock signal based on the second set of reference clocks.
