Method and apparatus for serial communication using clock-embedded signals

Abstract

An apparatus for serial communication using embedded clock signals is presented. The apparatus includes a clock-embedded signal generator for generating a data signal and a data-bar signal displaying a data stream according to relative positions and, when an external clock is input, generating a clock-embedded data signal and a clock-embedded data-bar signal by equalizing the data signal and the data-bar signal. The apparatus also includes a clock-embedded signal recovery unit for recovering the data signal and the data-bar signal according to relative positions of the clock-embedded data signal and the clock-embedded data-bar signal, and recovering synchronization information of the clock by detecting when the clock-embedded data signal and the clock-embedded data-bar signal are equalized. A method for serial communication using embedded clock signals is also presented.
