Abstract
An edge alignment apparatus includes: a signal source, for generating a first and a second square wave signals; a phase delay circuit, for receiving the first and the second square wave signals to generate a delayed first and a delayed second square wave signals; a data circuit, for generating a third square wave signal according to the delayed second square wave signal; and a phase calibrating circuit, for receiving the third square wave signal and the delayed first squared wave signal to generate at least one phase tuning signal to the phase delay circuit for tuning a phase difference between the delayed first and the delayed second square wave signals, such that a signal edge of the third square wave signal aligns with that of the first square wave signal. The first, second and third square wave signals have a same frequency.
