  • Patent number: 11855817
    Abstract: A first physical layer device includes a first transmitter and a first receiver. The first transmitter transmits first data to a second physical layer device over a medium at a first line rate during a first transmit period. The first receiver is configured to not receive data during the first transmit period and an echo reflection period occurring after the first transmit period. The echo reflection period is based on a length of the medium between the first physical layer device and the second physical layer device. The first receiver is configured to, after the echo reflection period, receive second data from the second physical layer device over the medium at a second line rate that is less than the first line rate.

  • Patent number: 11671142
    Abstract: Embodiments of the present disclosure utilizes the natural properties of RFI noise on a wireline link. Since differential RFI noise in the system has some correlation with the common mode noise on the cable, a replica of RFI noise can be regenerated by an adaptive filter based on information about the common mode noise. The replica RFI is subtracted from the equalizer output prior to the data decision circuitry or slicer. In this method, the system does not require expensive cable, nor does the equalizer suffer additional loss due to an RFI notch filter. Since RFI can be detected and mitigated, this information can also be coupled to safety systems to increase functional safety under high EMI conditions.

  • Patent number: 11165718
    Abstract: A physical layer device for transmitting and receiving Ethernet data includes a transmit path including a first transmitter configured to operate at a first speed, communicate with a first medium access controller (MAC), and transmit first Ethernet data from the MAC on a cable. A receive path includes a first receiver configured to operate at a second speed that is different than the first speed, communicate with the first MAC, and receive second Ethernet data from the cable and output the second Ethernet data to the first MAC.
