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.
