Abstract: The present invention provides a way of placing a physical layer device into a standby mode. After a link is established between multiple devices, a determination is made whether the device has data to transmit or whether a standby request was received from a link partner. If a standby request was received or the device has no data to transmit, standby mode is entered. In standby mode, unneeded circuitry is powered down. A transmitter in a channel and a receive path in a separate channel remain powered. While operating in standby mode, the PHY layer continuously transmits a standby code on the one or more channels that are not powered down. Standby mode is discontinued when a transceiver has data to transmit or when energy is detected on the powered down channels. Standby mode is also discontinued when no standby code is received, indicating a disconnect between devices.

Abstract: Aspects of a method and system for interference cancellation substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims. In this regard, a receiver may be operable to receive a differential signal via a differential channel, and to sense a common mode signal on the differential channel. A frequency range in which interference is present in the common mode signal may be determined. The differential signal and the common mode signal may be filtered to attenuate frequencies outside the determined frequency range. A phase and/or amplitude of the filtered common mode signal may be adjusted based on the filtered differential signal and the adjusted and filtered common mode signal may be subtracted from the received differential signal. The common mode signal may be sensed via a pair of resistors coupled to the differential channel.
