摘要： Methods, apparatus and systems for de-correlating training pattern sequences for high-speed links and interconnects. The high-speed links and interconnects employs multiple lanes in each direction for transmitting and receiving data, and may be physically implemented via signal paths in an inter-plane board such as a backplane or mid-plane, or via a cable. During link training, a training pattern comprising a pseudo random bit sequence (PBRS) is sent over each lane. The PBRS for each lane is generated by a PBRS generator based on a PRBS polynomial that is unique to that lane. Since each lane employs a different PRBS polynomial, the training patterns between lanes are substantially de-correlated. Link negotiation may be performed between link endpoints to ensure that the PBRS polynomials used for all of the lanes in the high-speed link or interconnect are unique. Exemplary uses include Ethernet links, Infiniband links, and multi-lane serial interconnects.

摘要： Methods, apparatus and systems for implementing Physical Media Attachment (PMA) alignment and rapid transition from a link training mode to a data mode for next-generation high-speed Ethernet links including a 100 Gbps Ethernet link. Training frames are transmitted between first and second Ethernet interfaces on opposing ends of the link in a pair-wise manner, with a first training frame being sent from a first Ethernet interface and a second training frame being returned from the second Ethernet interface. The training frames have a length that is different that the length of Physical Media Attachment (PMA) frames, and the returned training frames include receiver readiness status indicia identifying a readiness status of a local receiver port, frame alignment offset data identifying a relative offset between a training frame and a predetermined location in a PMA frame, and countdown data. The readiness status indicia, frame alignment offset data and countdown data are employed to facilitate a rapid transition from the link training mode to the data mode.

摘要： Methods for implementing mini-mezzanine Open Compute Project (OCP) plug-and-play Network PHY Cards and associated apparatus. In accordance with one aspect, the MAC (Media Access Channel) and PHY (Physical) layer functions in one or more communication protocol stacks are split between a MAC block in a Platform Controller Hub (PCH) or processor SoC and a PHY card installed in a mezzanine slot of a platform and including one or more ports. During platform initialization operations, configuration parameters are read from the PHY card including a PHY card ID, and a corresponding configuration script is selected and executed to configure the PHY card for use in the platform. The configuration parameters are also used to enumerate PCIe devices associated with physical functions and ports supported by the PHY card.

摘要： Methods and apparatus for Ethernet auto-negotiation (AN) with parallel detect for 10G DAC or other non-auto-negotiated modes. AN base pages are transmitted from an Ethernet apparatus to advertise the ability to support at least one Institute of Electrical and Electronics Engineers (IEEE) 802.3 Ethernet specification supporting AN. A receiver and associated processing circuitry is configured to perform two detection modes in parallel, including a first detection mode that looks for a valid signal transmitted from an Ethernet link peer that does not support AN and a second detection mode looking for AN pages from an IEEE 802.3 Ethernet link peer that supports AN. If the link peer does not support AN, an Ethernet link is set up to use signaling in accordance with the Ethernet specification that does not support AN. If the link peer supports AN, an Ethernet link is set up using a corresponding IEEE 802.3 Ethernet link supporting AN. Supported non-AN Ethernet links include 10G DAC links.

摘要： Technologies for capabilities exchange include a network port logic having a communication link coupled to a remote link partner. The port logic transmits local host loss information to the link partner and receives remote host loss information from the link partner. The port logic may communicate the host loss information via an autonegotiation base page, an autonegotiation next page, or a PMD control frame. The port logic determines total channel loss based on the local host loss, the remote host loss, and cable loss. The port logic may bring the communication link up without forward error correction (FEC) if the total channel loss is less than a FEC limit, may bring the link up with FEC if the total loss is less than a specification limit, or may not bring the link up if the total channel loss is above the specification limit. Other embodiments are described and claimed.
