Abstract
An alternate clock apparatus and method configured to reduce noise in selected frequency bands in an electronic device such as a communication device is described. In one embodiment the alternate clock includes a ring oscillator to generate multiple time shifted signals which may then be combined to generate clock signals at alternate frequencies to a primary reference. A resynchronization circuit may be coupled to the ring oscillator to periodically resynchronize the ring oscillator to a reference signal to reduce alternate clock jitter.
