Abstract
An oscillator circuit (200) is provided having a crystal oscillator (202) operating in a first oscillator mode to produce an oscillator output signal (201). The oscillator output signal (201) has a desired frequency of operation. The oscillator circuit (200) also includes switches (206A and 206B) for selectively forcing the crystal oscillator (202) to operate in a second oscillator mode in order to shift the frequency of the oscillator output signal (201).
