Abstract
A tunable clock circuit has a dual overlapping digital to analog converter (DAC) and an oscillator. The dual overlapping DAC provides a first output selectable with a first resolution and a second output selectable with a second resolution. The first resolution is different from the second resolution. The oscillator has a first input coupled to the first output of the dual overlapping DAC, a second input coupled to the second output of the dual overlapping DAC, and an output providing a clock output signal.
