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.
Claims20
A Physical Layer (PHY) transceiver, comprising:
- communication circuitry comprising a digital filter, the communication circuitry configured to communicate signals, using the digital filter, over a network link;
- and
- a controller 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.
A method for operating a Physical Layer (PHY) transceiver that includes a digital filter, the method comprising:
- communicating signals using the digital filter over a network link;
- monitoring a temperature pertaining to the PHY transceiver;
- and
- in response to detecting an actual or predicted over-temperature condition, degrading a functionality of the digital filter so as to reduce power dissipation in the PHY transceiver.
