Abstract
A timing crystal oscillator circuit that may be tuned after production. The circuit generally comprises a microprocessor configured to present one or more control signals, one or more load devices that may be activated in response to the control signals and a crystal oscillator for presenting an output signal having a frequency which is generally dependent on the number of load devices activated.
