Abstract: A method and apparatus for transmit signal pulse shaping. Automotive vehicle manufacturers that incorporate electronic components into an automotive vehicle must consider emission requirements masks that can be dependent on particular geographic markets as well as the other electronic components contained within a particular automotive vehicle design. A physical layer device is provided that can be configured to operate in multiple emissions configurations using configurable parameters.

Abstract: A method for frequency synchronization of a multiport device may include recovering a clock frequency of a master port of a first device that is linked to the multiport device at a slave port of the multiport device. A clock frequency of the slave port may be locked to the recovered-clock frequency of the master port of the first device. Frequency data may be stored in a first frequency register associated with the slave port. The stored frequency data may include a difference between the recovered-clock frequency of the master port of the first device and a local-clock frequency of the multiport device. A clock frequency of one or more master ports of the multiport device may be synchronized with the locked clock frequency of the slave port by coupling the first frequency register to frequency registers associated with one or more master ports.

Abstract: A vehicle communication network device includes a transceiver configured to communicatively couple with a remote transceiver of another vehicle communication network device via a wired media and processing circuitry coupled to the transceiver.The device detects interference on the wired media that exceeds an interference threshold level. Upon the detection, the device enters a quiet mode during which no data is transmitted on the wired media. After exiting the quiet mode, the device enters an idle mode during which known data is transmitted on the wired media and during which the device receives known data from the remote transceiver. The device retrains its transceiver based upon the known data and after retraining the transceiver, exchanges data with the remote transceiver. The device may also buffer data for transmission, upon the detection, determine buffered data that was likely corrupted by the interference, and after retraining, retransmit the determined buffered data.
