    Abstract: Systems and methods are disclosed for spur mitigation for pulse signal drivers in radio frequency (RF) devices. An RF integrated circuit includes RF circuitry and analog-to-digital (ADC) circuitry. The RF circuitry operates using a local oscillator (LO) clock to receive and/or transmit RF signals, and the ADC circuitry samples one or more analog input signals and has internal timing based upon a raw digital clock. A retime circuit receives the raw digital clock and the LO clock and has a retimed clock as an output. The retimed clock represents the raw digital clock retimed with the LO clock. While other digital circuitry is timed using the raw digital clock, one or more drivers are timed by the retimed clock and provide pulse output signals to output pads. Having the drivers timed with the retimed clock and other digital circuitry timed with the raw digital clock improves overall performance.

    Abstract: An apparatus includes a detector to detect an idle state of a communication link that communicates bursts or packets of information. The apparatus also includes an oscillator having low-power and normal modes of operation. The oscillator makes a transition to the low-power mode during the idle state of the communication link. The oscillator leaves the low-power mode of operation and enters the normal mode of operation when the communication link is in a non-idle state.

    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.
