1. An apparatus comprising:
an adapter comprising:
a first interface to couple to a particular device, wherein link layer data is to be communicated over the first interface;
a second interface to couple to a physical layer (PHY) device, wherein the PHY device comprises a plurality of wires to implement a physical layer of a die-to-die link, the die-to-die link couples the adapter to another adapter on another die via the PHY device, and the second interface comprises:
a data channel to communicate the link layer data over the physical layer; and
a sideband channel to communicate sideband messages between the adapter and the other adapter over the physical layer; and

circuitry to implement a logical PHY for the die-to-die link.
