Abstract: A primary device implementing the subject system of link establishment for single pair Ethernet may include at least one processor circuit. The at least one processor circuit may be configured to transmit a first synchronization sequence to a secondary device and to subsequently detect a second synchronization sequence, different than the first, transmitted by the secondary device. The synchronization sequences may be pseudo-noise sequences that have strong autocorrelation characteristics. The at least one processor circuit may be configured to wait a predetermined amount of time after completing the detection of the second synchronization sequence, and then may initiate a training stage. The training stage may include exchanging scrambler states of additive scramblers used by the primary and secondary devices. The at least one processor circuit may be configured to enter a data mode upon completion of training. In the data mode, data is forward error correction encoded and then scrambled.

Abstract: A transceiver, a communication system and an associated method thereof for reducing overall power consumption and complexity of the transceiver that operates over short reach twisted pair cables. The analog front end (AFE) of the transceiver communicates over at least one twisted pair that is configured only for transmission of data streams and communicates over at least one twisted pair that is only for reception of data streams. The transceiver includes circuitry that generates multiplexed and demultiplexed data streams for communication with the analog front end. Additionally, the transceiver utilizes at least certain portions of signal processing circuitry and AFE of a 10 GBASE-T transceiver or the like.
