An apparatus and system for controlling traffic on an on-chip network. Embodiments of the apparatus comprise single-ended transmission circuitry and single-ended receiving circuitry on a first chip for coupling with a second chip, the transmission circuitry having impedance matching and lacking equalization, the receiving circuitry lacking equalization, the transmission circuitry and the receiving circuitry having statically configurable features and organized in clusters, wherein the clusters have the same physical layer circuitry design for different configurations of the configurable features, the configurable features including half-duplex mode and full-duplex mode, wherein the first chip and the second chip are on the same package, and wherein a plurality of conductive lines for coupling the first chip with the second chip are matched.
