Abstract
A timing calibration device for calibrating a timing relationship between a clock signal and a first signal includes: an input port, receiving the clock signal through a clock transmission path, and receiving the first signal through a first path; and a calibrator. The calibrator includes: a first sampling circuit, sampling the first signal according to the clock signal to generate a first sample result; a control circuit, determining that the first sample result is valid when the first sampling result includes a transition edge of the first signal; and a first edge adjusting circuit, adjusting one of a transition edge of the clock signal and the transition edge of the first signal when the first sample result is valid to satisfy a predetermined timing relationship.
