Abstract: An extender includes a transmitter and a receiver for transmitting a first and a second differential data signals and a differential clock signal. The transmitter combines a positive clock signal of a differential clock signal with a first differential data signal and combines a negative clock signal of the differential clock signal with a second differential data signal, thereby respectively forming a first and a second composite differential signals. The receiver includes a first impedance unit extracting the positive clock signal from the first composite differential signal, a second impedance unit extracting the negative clock signal from the second composite differential signal, and a recovery unit receiving the positive and negative clock signals and forming the differential clock signal. The frequency of the extracted first and second differential data signals are ten times or more of the frequency of the differential clock signal.
