Abstract
A system and method of varying frequency is disclosed. A first oscillator in a phase-locked loop (PLL) maintains a first frequency as part of the PLL lock. A second oscillator having a control coupled to the PLL can be modified to generate a frequency different than that of the PLL. This is accomplished while maintaining lock of the PLL.
