Abstract: A physical layer (PHY) is coupled to a serial, differential link that is to include a number of lanes. The PHY includes a transmitter and a receiver to be coupled to each lane of the number of lanes. The transmitter coupled to each lane is configured to embed a clock with data to be transmitted over the lane, and the PHY periodically issues a blocking link state (BLS) request to cause an agent to enter a BLS to hold off link layer flit transmission for a duration. The PHY utilizes the serial, differential link during the duration for a PHY associated task selected from a group including an in-band reset, an entry into low power state, and an entry into partial width state.

Abstract: Embodiments include a pulsed decision feedback equalization (DFE) circuit. The DFE circuit may include a current integrating summer (CIS) circuit that passes one or more data signals on respective data nodes based on an input data signal and a clock signal. The DFE circuit may further include a correction circuit, such as a current digital-to-analog converter (IDAC) circuit, that may provide a correction circuit to a data node based on a prior bit of the input data signal. The correction circuit may provide a conductive path between a current source of the correction circuit and the data node for a time period that is less than the unit interval (UI) of the clock signal and/or data signal. The DFE circuit may include a plurality of correction circuits to provide respective correction signals based on different prior bits of the input data signal. Other embodiments may be described and claimed.

Abstract: A set of training sequences is generated, each training sequence to include a respective training sequence header, and the training sequence header is to be DC-balanced over the set of training sequences. The set of training sequences can be combined with electric ordered sets to form supersequences for use in such tasks as link adaptation, link state transitions, byte lock, deskew, and other tasks.
