  • 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.
