Abstract
A method and apparatus are provided for implementing a fault tolerant phase locked loop (PLL). The PLL circuit includes a divide by N circuit defined by a plurality of sub-divide by N functions, each providing a feedback frequency signal applied to a voter circuit. The voter circuit provides an output feedback frequency signal based upon a majority vote of the sub-divide by N functions.
