Abstract
Systems and methods for reducing interference caused by leakage of signals generated by a spread spectrum phase lock loop (SS PLL). The system and method uses a sinusoidal spreading signal to spread the output of a SS PLL. A notch filter tracks the frequency of the output of the SS PLL to steer the notch in the filter to the instantaneous frequency output from the SS PLL, thus allowing the notch filter to be placed in the path of signals that have unwanted leakage from the SS PLL.
