  • Patent number: 11309966
    Abstract: A method and apparatus for latency control in an optical network. A management node such as an OLT in a PON sends a discovery message intending to prompt joining network nodes such as ONUs to send a response on a first wavelength during a quiet window established for this purpose. When a response is received, a secondary upstream-transmission wavelength is assigned to the ONU. When the ONU sends data upstream according to a schedule calculated by the ONT, which schedule may include transmission times using the assigned secondary wavelength. In this case, the assigned secondary wavelength will be scheduled using a relatively smaller or no quiet window. This scheduling may be determined in part by the service or services used by the ONU.

  • Publication number: 20130336081
    Abstract: Embodiments of the invention relate to a state-monitoring memory element. The state-monitoring memory element may have a reduced ability to retain a logic state than other regular memory elements on an IC. Thus, if the state-monitoring memory elements fails or loses state during testing, it may be a good indicator that the IC's state retention may be in jeopardy, possibly requiring the IC to be reset. The state-monitoring memory element may be implemented by degrading an input voltage supply to the state-monitoring memory element across a diode and/or a transistor. One or more current sources may be used to stress the state-monitoring memory element. A logic analyzer may be used to analyze the integrity of the state-monitoring memory element and trigger appropriate actions in the IC, e.g., reset, halt, remove power, interrupt, responsive to detecting a failure in the state-monitoring memory element.

  • Patent number: 8564252
    Abstract: A circuit for charging a capacitive load to a reference voltage in a capacitive sensor measurement circuit includes a reference buffer, a boost buffer, and drive logic. The reference buffer and the boost buffer are coupled with the capacitive load to be charged. The boost buffer first charges the capacitive load towards the reference voltage at a first rate of charging, and then ceases charging. The reference buffer subsequently continues charging at a slower second rate to settle the voltage across the capacitive load to within a tolerable range of the reference voltage.

  • Patent number: 8049569
    Abstract: A clock generation circuit is provided for improving the accuracy of a low power oscillator circuit contained therein. The clock generation circuit includes a crystal-less oscillator having at least two distinct frequency modes, including a low frequency mode and a high frequency mode. In some cases, the crystal-less oscillator may be adapted to generate a first clock frequency with relatively high accuracy and a second clock frequency with relatively low accuracy. A calibration and control circuit is included within the clock generation circuit for increasing the accuracy of the second clock frequency. In particular, the calibration and control circuit increases accuracy by using the first clock frequency to calibrate the second clock frequency generated by the same crystal-less oscillator. A system comprising the clock generation circuit and methods for operating a crystal-less oscillator having at least two distinct frequency modes are also provided herein.
