Apparatuses and systems associated with expansion card design with a coherent connector to provide for coherent communication are disclosed herein. In embodiments, a circuit card may comprise an integrated circuit (IC), a first connector to couple the IC to a processor of a computer device, the first connector to provide for non-coherent communication between the IC and the processor, and a second connector to couple the IC to the processor, the second connector to provide for coherent communication between the IC and the processor. Other embodiments may be described and/or claimed.

Circuit card with coherent interconnect

A network fabric physical layer includes a driver coupled to a receiver via a bus, which implements a multiphase encoded protocol. A multiphase sequencer sequences (data or command/control) words for the driver. The driver outputs the sequenced words onto the bus as a differential multiphase encoded waveform. The receiver receives the differential multiphase encoded waveform and performs statistical analysis to determine data integrity checking. The bus is a concurrent differential bi-directional bus and each transmitting driver includes impedance compensation circuitry on both ends of a transmission line so that each drives its signal value with the impedance characteristics of the transmission line. The receiver also includes jitter immunity.
