Abstract: A system and method of training communication paths between Ethernet devices. The method includes establishing, between an integrated circuit (IC) device and an Ethernet device, a first communication path to transmit a first signal at a first data rate to the Ethernet device and a second communication path to receive a second signal from the Ethernet device. The method includes executing a startup training sequence by transmitting a first set of training signals over the first communication path to optimize communication to the Ethernet device and receiving a second set of training signals over the second communication path to optimize communication from the Ethernet device. The method includes operating, upon completion of the startup training sequence, in a data mode to transmit the first signal via the first communication path and receive the second signal via the second communication path.

Abstract: A method of Link Synchronization (LS) signal generation is robust to the presence of the clock frequency offset and is used to enable LS function in crystal-less mode of operation. In the method of LS signal generation, the binary chirp (linearly frequency modulated) signal is used.

Abstract: A system and method of processing Automotive Ethernet and High-Speed Ethernet signals. The method includes forming a first data path according to a first transmission protocol and a second data path according to a second transmission protocol. The method includes selecting the first data path to receive a first bitstream compliant with the first transmission protocol at a first data rate. The method includes encoding the first bitstream using a first encoding scheme to produce a first encoded bitstream. The method includes upsampling the first encoded bitstream to produce an upsampled bitstream at a different data rate. The upsampled bitstream aligns with transmission requirements of a Physical Medium Attachment (PMA) device. The method includes forwarding the upsampled bitstream to the PMA device.
