    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.

    Abstract: Multiplexed packet local area networking using an Ethernet physical layer device. In one embodiment, a network device having dual port Ethernet physical layer devices can be configured to receive a packet on a first Ethernet port. The network device can extract first packet data that is destined for the network device from the data section of the packet and insert second packet data that is destined for the gateway node into the packet to produce a modified packet. The modified packet is then transmitted by the network device over a second Ethernet port.

    Abstract: Common-mode termination within communication systems. Termination is implemented with respect to two respective portions of a system: the intentional signaling within a communication system as well as any unintentional signaling which may be coupled into the system. Such unintentional signaling may be incurred in a variety of ways including via interference which may be generated by the system itself or by other devices or components external to the system. In addition, such unintentional signaling made be characterized as common-mode (CM) signaling, in that, it generally affects different respective portions of the system similarly or in the same manner. Various communication systems may include two or more devices implemented therein, that effectuate signaling via one or more communication links there between. Appropriate termination is made with respect to both the intentional and unintentional signaling portion of the system using any of a variety of impedance types (e.g., resistors, capacitors, inductors, etc.).
