• H03L 2207/04 Modifications for maintaining constant the phase-locked loop damping factor when other loop parameters change
• H03L 2207/05 Compensating for non-linear characteristics of the controlled oscillator
• H03L 2207/06 Phase locked loops with a controlled oscillator having at least two frequency control terminals
• H03L 2207/08 Modifications of the phase-locked loop for ensuring constant frequency when the power supply fails or is interrupted, e.g. for saving power
• H03L 2207/10 Indirect frequency synthesis using a frequency multiplier in the phase-locked loop or in the reference signal path
