Disclosed is a method of managing power consumption of a system with a first device coupled to a communication device of a communication network by way of a first communication link and a second device coupled to the communication device of the communication network by way of a second communication link.

Power management of networked devices

A network-centric, power management system and method is disclosed for monitoring and controlling device nodes attached to a network. The monitoring and controlling includes collecting and processing information available on the network about the device nodes and using the collected information to manage power on the device nodes.

A shared data and clock recovery circuit including a clock synthesizer for generating sampling signals having different phases, a multiple transition detector for receiving a data stream and sampling signals, and for detecting edges in a data stream in response to the sampling signals, a counter and accumulator for detecting the time occurrences and total number of edges, and for performing weighted average calculation to select one of the phases, a decision circuit for detecting the phase difference between a source clock and a local clock such that if the PPM difference between the source clock and the local clock is at least 200 PPM, then selection of a phase is based upon stored historical information, and if the PPM difference between the source clock and the local clock is less than 200 PPM, then selection of a phase is based on a weighted averaging calculation.
