ABSTRACT:
A high resolution digitally controlled oscillator is in the form of a digital frequency divider, which uses calculation logic to utilize both the rising edge and the falling edge (start edge and stop edge) of the input clock pulses to provide the capability of alternating between two adjacent frequencies. This results in significantly improved resolution, since the division ratio is not dependent upon any integral number of clock periods.
