Abstract: A communication technique for energy efficient Ethernet (EEE) employs a systematic block forward error correcting code (FEC). The technique aligns a low power idle (LPI) refresh signal with the FEC frame. The refresh signal includes a known reference sequence, FEC systematic symbols, and FEC parity symbols. The technique may apply shortened FEC encoding and decoding on the partial data symbols and the parity symbols.

Abstract: A device for common mode (CM) clamping in wired communication includes a first circuit and a second circuit. The first circuit is configured to sense a voltage signal across clamp terminals and to generate an output voltage signal based on the sensed voltage signal. The second circuit is configured to compare the output voltage signal with a reference voltage, to generate a pair of current signals based on a result of the comparison, and to provide the pair of current signals to the clamp terminals. The pair of current signals includes a matched pair of CM current signals. The clamp terminals, upon coupling to nodes of a main circuit provide a desired CM impedance between the nodes of the main circuit. The device can be coupled to the main circuit in conjunction with one or more off-chip magnetic components.

Abstract: A primary device implementing the subject system of link establishment for single pair Ethernet may include at least one processor circuit. The at least one processor circuit may be configured to transmit a first synchronization sequence to a secondary device and to subsequently detect a second synchronization sequence, different than the first, transmitted by the secondary device. The synchronization sequences may be pseudo-noise sequences that have strong autocorrelation characteristics. The at least one processor circuit may be configured to wait a predetermined amount of time after completing the detection of the second synchronization sequence, and then may initiate a training stage. The training stage may include exchanging scrambler states of additive scramblers used by the primary and secondary devices. The at least one processor circuit may be configured to enter a data mode upon completion of training. In the data mode, data is forward error correction encoded and then scrambled.

Abstract: A local area network (LAN) backbone is implemented within an environment such as a self-contained environment (e.g., an automobile, an aircraft, a train, a ship, and/or any other environment). The LAN backbone is affected by AWGN, NBI, and/or impulse noise (noise). The LAN backbone supports communications based on an Ethernet communication protocol (e.g., a 1000Base-T1 based system that includes at least one single twisted pair). A device receives a first LDPC coded signal via the LAN backbone and decodes it to recover an input signal of a control system. The device also uses soft information generated during the decoding to compensate for the noise affecting the LAN backbone and then processes the input signal to generate a control signal for the control system. The device then and encodes the control signal to generate a second LDPC coded signal and transmits the second LDPC coded signal via the LAN backbone.

Abstract: System and method for energy efficient Ethernet with asymmetric traffic profiles. A low power mode such as a low power idle mode is typically leveraged when both direction of a link do not have data traffic to transmit. Where only one direction of a link has data traffic to transmit, a physical layer device can transition from a full duplex mode to a simplex mode to produce energy savings (e.g., disabling cancellation circuitry).

Abstract: In the subject system for remote monitoring and configuration, management of a remote physical layer device may be performed by receiving, at a local physical layer device, an incoming message of a first communication format from a controller device. The incoming message may include a request intended for the remote physical layer device that is communicatively coupled to the local physical layer device over a transmission line carrying a data channel and a supplemental channel. The incoming message may be parsed into an outgoing message of a second communication format for sending to the remote physical layer device through the supplemental channel. The local physical layer device may receive a response from the remote physical layer device through the supplemental channel. The local physical layer device may convert the response from the second communication format into the first communication format for sending the converted response back to the controller device.

Abstract: A system to implement a communication line coding scheme using a non-complex bit-to-symbol mapping, a forward error correction (FEC) coding, and an additive bit scrambler after the FEC at the PHY layer is provided. The system may be a part of or implemented by an automobile component. The system may be a PHY device configured to convert data from the MAC layer into 2D-PAM3 symbols that are transmitted across a communication link at a predetermined transmission rate, such as to be compliant with a communication standard. The PHY device may select characteristics of the conversion, such as the FEC coded symbol, based on the target transmission rate. The PHY device may include a transceiver, and may convert the data from MAC layer to PHY layer and back.
