  • Robust low rate data channel in LPI mode for energy-efficient ethernet applications
    Patent number: 9577787
    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.
    Type: Grant
    Filed: February 20, 2015
    Date of Patent: February 21, 2017
    Assignee: BROADCOM CORPORATION

  • Network interface with low power data transfer and methods for use therewith
    Patent number: 9207740
    Abstract: A network interface includes a physical layer device coupled to a network link. A media access control module communicates with a link partner over the network link. An energy controller monitors a link utilization level of the network link and transitions, in response to the monitoring, the media access control module and the physical layer device to a low power idle mode, wherein the low power idle mode includes periodic transmission of a plurality of refresh frames in a refresh cycle and wherein at least one of the plurality of refresh frames is modified to include at least one first data payload.
