  • Method and apparatus for on-chip voltage controlled oscillator function
    Patent number: 8165199
    Abstract: This invention uses a flying adder frequency synthesis circuit to provide the required frequency adjustments to accommodate the varying encoding density of a MPEG2 video data stream. This invention adjusts the local clock based on the information extracted from the program clock reference signal in the incoming data. This invention replaces an external or internal voltage-controlled crystal oscillator using a phase locked loop circuit on the video processing integrated circuit.
    Type: Grant
    Filed: October 20, 2008
    Date of Patent: April 24, 2012
    Assignee: Texas Instruments Incorporated
    Inventors: Liming Xiu, Grady Cook, Daniel Dudek, Hongbing Lian, Yihe Hu, Christopher S. Tracy
