Abstract

A device is for detecting a relative positioning of two clock signals including a fast clock signal and a slow clock signal. The fast clock frequency may be n times greater than a slow clock frequency, and n includes an integer greater than 1. The device includes a phase logic signal generator for generating a phase logic signal from the two clock signals by assigning a predetermined logic value to the phase logic signal when a rising edge of the fast clock signal matches a predetermined location of the slow clock signal.
