Abstract
An apparatus includes a phase frequency detector having a detector output and first and second inputs, the phase frequency detector configured to provide a phase difference signal at the detector output responsive to the first and second inputs. The apparatus also includes a gain controller having a controller input and a controller output, the controller input coupled to the detector output, and the gain controller configured to provide a digital value at the controller output responsive to the phase difference signal and a duty cycle. The apparatus also includes a pulse generator having a generator output and first and second generator inputs, the first generator input coupled to the controller output, the second generator input coupled to the second detector input, the pulse generator configured to provide a generator signal at the generator output responsive to the digital value and the second generator input.
