Abstract
A phase generating apparatus generates an output clock having a desired phase according to a digital signal. The apparatus includes a phase selecting unit and a phase generating unit. The phase selecting unit selects one of a plurality of input clocks according to a portion of bits of the digital signal to generate a reference clock. Each of the input clocks respectively has a difference phase. The phase selecting unit divides the frequency of the reference clock, and selectively delays the frequency-divided reference clock according to another portion of bits of the digital signal to generate the output clock.
