Abstract: Systems and methods for implementing bi-directional synchronization propagation between first and second communication devices are provided. The devices are arranged in a loop-timing configuration. A method includes detecting, by the second communication device, a switching signal comprising an indication to switch a timing role of the second communication device and engaging, by the second communication device, in a synchronization handshake with the first communication device over a communication link based on the detection of the switching signal. Engaging in the synchronization handshake includes determining whether the first communication device is configured to support bi-directional synchronization propagation. The method includes switching the timing role of the second communication device based on the synchronization handshake.

Abstract: A system for reduced pair Ethernet transmission. The system includes an interleaver that is operable to receive sets of four code symbols from a physical channel sub-layer (PCS) encoder, wherein each code symbol of each set of four code symbols is associated with one of four channels, and interleave the sets of four code symbols to generate a plurality of interleaved code symbols. The system further includes a serializer that is operable to serialize the plurality of interleaved code symbols to generate a plurality of interleaved and serialized code symbols. The system further includes a transmitter that is operable to transmit the plurality of interleaved and serialized code symbols over an Ethernet medium comprising a single twisted pair of wires.

Abstract: Aspects of a method and system for unconstrained frequency domain adaptive filtering include one or more circuits that are operable to select one or more time domain coefficients in a current filter partition. A value may be computed for each of the selected one or more time domain coefficients based on a corresponding plurality of frequency domain coefficients. The corresponding plurality of frequency domain coefficients may be adjusted based on the computed values. A subsequent plurality of frequency domain coefficients in a subsequent filter partition may be adjusted based on the computed values. Input signals may be processed in the current filter partition based on the adjusted corresponding plurality of frequency domain coefficients. A time-adjusted version of the input signals may be processed in a subsequent filter partition based on the adjusted subsequent plurality of frequency domain coefficients.
