Abstract: Systems and methods for using a physical layer transceiver (PHY) of an automobile to avoid data signal collision on a high noise or interference automotive multi-drop communication link are provided. A signal is received at a first PHY via a multi-drop communication link in a high noise or interference automotive environment. The received signal is separated into a first spectral component corresponding to a first logic level and into a second spectral component corresponding to a second logic level. Based on analysis of the first and second spectral components, respectively, a determination is made as to whether a second PHY device is concurrently transmitting data on the link, by determining whether both the first and second logic levels are detected in the first and second spectral components within a threshold period of time of one another.

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.
