Abstract: A digital phase-locked loop has a digitally controlled oscillator with a first coarse tuning field for coarse tuning of the oscillator frequency, a second coarse tuning field for tuning of the oscillator frequency at finer intervals than the first coarse tuning field, and a fine tuning field for tuning the oscillator to an output frequency at finer intervals than the second coarse tuning field. The second coarse tuning field provides open loop tuning and is linear and connected parallel to the first coarse tuning field. The second coarse tuning field provides wide field temperature compensation and frequency error determination at start up based on an interpolated frequency value obtained prior to start up. Faster settling is provided with less complex algorithms.
