摘要： A reconfigurable Ethernet physical layer (PHY) is operable in at least a first mode and a second mode. The PHY includes signal processing circuitry to process communications of a first type or a second type during the first mode of operation, and to process multiple communications of the second type during the second mode of operation. A plurality of transceivers is coupled to the signal processing circuitry. Each transceiver of the plurality of transceivers includes a transmitting element and a receiving element. A switching element selectively couples the plurality of transceivers to a first set of communications channels or a second set of communications channels based on the mode of operation. Specifically, a number of communications channels in the second set of communications channels is greater than a number of transceivers of the plurality of transceivers.

摘要： An echo canceller and one or more near-end crosstalk (NEXT) cancellers in a receiver in a slave device are trained during a respective phase of a training sequence. During the respective phase, data is received from a master device while the slave device transmits data to the master device. The data received from the master device is predicted. Echoes and NEXT associated with the data transmitted to the master device are also received. The echo canceller and one or more NEXT cancellers are trained based in part on the predicted data.

摘要： An Ethernet device is disclosed that may reduce transient currents and/or power consumption while entering and exiting a low power mode by selectively powering-on and/or powering-off a number of transceiver components at different times (e.g., in a staggered manner). The transient currents and/or power consumption may be further reduced by assigning different quiet period durations to different transceiver chains, for example, to minimize the number of transceiver components that enter and/or exit the low power mode at the same time.

摘要： A method for operating a receiver is disclosed. The receiver may receive, over a channel from a transmitter, a first data bit at a first period of time. The receiver may receive, over the channel, a second data bit at a second period of time subsequent to the first period of time. The first and second data bits each have either a first logical value corresponding to a voltage greater than zero volts or a second logical value corresponding to a voltage less than or equal to zero volts. The receiver performs a coefficient adaptation operation, using the first data bit, to adjust one or more coefficients of a decision feedback equalizer of the receiver only when the logical value of the first data bit is equal to the logical value of the second data bit.

摘要： A method and apparatus of clock recovery is disclosed. A communications device matches the frequency of a local clock signal with the frequency of a transmit clock signal of a transmitting device based on a first set of signals received from the transmitting device during a low-speed information exchange. The low-speed information exchange may correspond to an autonegotiation operation, wherein each of the transmitting device and the communications device declares its communication capabilities to the other device. The communications device then determines a frequency offset to be applied to the local clock signal during a high-speed data communication with the transmitting device. During the high-speed communication, the communications device may apply the frequency offset to the local clock signal and match the phase of the receive clock signal with the phase of the transmit clock signal based on a second set of signals received from the transmitting device.
