Abstract
An apparatus for transmitting data signals includes a logic unit configured to generate an encoded clock signal in response to a clock signal and a first data signal, and a demultiplexer configured to receive the encoded signal, the first data signal, and a second data signal, and to output odd-numbered data signals of the received signals at a first edge of the clock signal and even-numbered data signals of the received signals at a second edge of the clock signal. A data state elimination block is configured to receive the signals and to invert one of the received signals if logic levels of the signals are the same. An apparatus for receiving data signals according to some embodiments of the invention includes a plurality of termination resistors connected between a corresponding pad and a power source, a plurality of differential amplifiers configured to amplify a voltage difference between corresponding pads, and a logic unit configured to restore a clock signal from signals received from two of the differential amplifiers.
