Patents by Inventor Yong Jheng Lin

Yong Jheng Lin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Frequency-locking device and frequency-locking method thereof
    Patent number: 7869492
    Abstract: The invention proposes a simple method suitable for automatically locking frequency during USB data communication. Based on the soft plug/unplug concept proposed in the contents and the error handling mechanism defined in the USB specification, we can calibrate the clock frequency of the digitally controlled oscillator (DCO), through the token packets, to be within the acceptable frequency when USB device is attached to the host controller.
    Type: Grant
    Filed: October 23, 2007
    Date of Patent: January 11, 2011
    Assignee: Sonix Technology Co., Ltd.
    Inventors: Yong Jheng Lin, Wen Hsiang Huang, Min-Yi Chen
  • Frequency-locking device and frequency-locking method thereof
    Patent number: 7633348
    Abstract: A frequency-locking device including a digitally-controlled oscillator (DCO) and a comparing unit is disclosed. The DCO is used for generating an output frequency signal. The comparing unit receives a Keep Alive signal from a universal serial bus (USB) and the output frequency signal, and compares the Keep Alive signal with the output frequency signal to generate a calibration signal. Then, the DCO adjusts the frequency of the output frequency signal according to the calibration signal to meet the USB specification for data communication.
