Abstract
A Physical Layer (PHY) transceiver includes communication circuitry and a controller. The communication circuitry includes a digital filter, and is configured to communicate signals using the digital filter over a network link. The controller is configured to monitor a temperature pertaining to the communication circuitry, and, in response to detecting an actual or predicted over-temperature condition, to degrade a functionality of the digital filter so as to reduce power dissipation in the communication circuitry.
