Techniques and mechanisms for exchanging communications which each represent a respective combination of data and clock signaling. In an embodiment, encoder logic generates a first signal pair, including encoding a first differential data signal pair with a first clock signal of a differential clock signal pair. The encoder logic further generates a second signal pair, including encoding a second differential data signal pair with a second clock signal of the same differential clock signal pair. In another embodiment, decoder logic receives and decodes the first signal pair and the second signal pair, wherein the decoding generates the first differential data signal pair, the second differential data signal pair and a clock signal.
