Abstract
A method of eliminating a runaway condition in a PLL includes the steps of: determining whether the PLL is locked to an input reference signal; when the PLL is not locked to the input reference signal, determining whether a frequency of an output signal generated by the PLL exceeds a prescribed maximum frequency; and when the frequency of the output signal generated by the PLL exceeds the prescribed maximum frequency, resetting the PLL to thereby eliminate the runaway condition.
