摘要: A system and method for accurately detecting an asynchronous frequency within a synchronous digital system. The improved preconditions the so that it does not introduce additional phase noise at low frequencies PLL. comprises digitally controlled oscillator, having preconditioner locked loop. receives input clock signal outputs modified is synchronized to master signal. loop output from version of preferably has higher bandwidth than PLL, operates shape synchronization frequencies. may then operate remove Due operation preconditioner,
