Interference suppression module and associated methods

Abstract

An interference suppression module for an Ethernet transceiver, the interference suppression module comprising circuitry configured to: receive a receiver output from a receiver module of the Ethernet transceiver, the receiver module configured to output a logic-high when a received voltage signal is higher than a receiver threshold, and output a logic-low when the received voltage signal is lower than the receiver threshold; receive an energy detection output from an energy detection module of the Ethernet transceiver, the energy detection module configured to output a logic-high when the received voltage signal is higher than a positive energy detection threshold or lower than a negative energy detection threshold, and output a logic-low when the received voltage signal is between the positive and negative energy detection thresholds; and output a predefined logic state to a receive pin of the Ethernet transceiver when the energy detection output is a logic-low.
