Abstract
A method, circuit and system for altering the power consumption in communication links. A type of noise and an amount of jitter in a signal transmitted across a communication link is measured. Upon determining the contribution of the measured noise to the measured jitter in the signal, the measured noise is classified based on such contribution and the intensity of the measured jitter. The power consumption in a component(s) of the communication link may be adjusted based on the classification of the measured noise. For example, if the measured noise is classified as being a low amount of noise, then the power consumption of the component(s) may be reduced such as by lowering the voltage of the power supply and/or reducing the complexity of the circuitry. By reducing the power consumption when the communication link is not subject to the worst-case condition, a savings in power consumption may be made.
