Abstract: A system for communicating information includes one device that communicates information via a communication link. The system also includes a second device to communicate information via the communication link. The second device includes a receiver to receive information from the communication link. The second device also includes an oscillator that provides at least one timing signal to the receiver. The oscillator is disabled when the communication link is in an idle state. The oscillator is enabled when the communication link is in a non-idle state.

Abstract: An apparatus includes analog or mixed-signal circuitry that operates in response to a first signal, and digital circuitry that operates in response to a second signal. The apparatus further includes a signal retiming circuit. The signal retiming circuit retimes an output signal of a digital signal source to reduce interference between the digital circuitry and the analog or mixed-signal circuitry by retiming edges of the output signal of the digital signal source to fall on cycle boundaries of the first signal.

Abstract: An apparatus includes a communication circuit coupled to a communication link, a wakeup detector, and a power control circuit. The communication circuit has a first state and a second state. The power consumption of the communication circuit is lower in the second state than in the first state. The wakeup detector is coupled to the communication link. The wakeup detector generates a wakeup signal to cause the communication circuit to make a transition from the second state to the first state in response to an occurrence of an event on the communication link. The power control circuit selectively supplies power to the communication circuit in response to the wakeup signal.
