Abstract
A network interface device operates in a normal transmit operating mode in which the network interface device continually receives transmission symbols from a link partner via the communication link. The network interface device determines that receive circuitry of the network interface device is to transition to a low power mode in response to receiving a sleep signal from the link partner. The network interface device then operates according to a quiet/refresh cycle of the low power mode to conserve power. The quiet/refresh cycle corresponds to a time schedule that includes a refresh time window in which receive circuitry of the network interface device is to be powered to receive a refresh signal from the link partner Immediately after transmission of the sleep signal, the network interface device transitions to a quiet time window of the time schedule in which the network interface device ignores transmissions from the link partner.
