Abstract
A clock signal extraction device for extracting a clock signal from a periodic data signal includes a phase detector for detecting a first phase difference between rising edges of said data signal and a rising edges clock signal and for detecting a second phase difference between falling edges of said data signal and a falling edges clock signal. The device also includes a clock generator for generating said rising edges clock signal so that said first phase difference is minimized, for generating said falling edges clock signal so that said second phase difference is minimized, and for generating said clock signal in dependence on said first phase difference and said second phase difference. A method for extracting a clock signal from a periodic data signal is related to the device.
