Leon Lei 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).

  • Methods and systems for providing variable clock rates and data rates for a SERDES
    Patent number: 7983374
    Abstract: A method and apparatus for varying an output clock signal frequency to match the frequency of an output data signal frequency for a SERDES circuit while maintaining a constant input clock frequency is shown. According to this method and apparatus, a PMA rate signal may control the frequency of the output clock while a datastrobe signal may be used to control the frequency of the data signal. Accordingly, the apparatus and methods may be used to produce an output data signal and a clock signal having frequencies that may be lower than the frequency of the input clock signal.
