A phase lock loop (PLL) circuit incorporates switched capacitive circuitry and feedback circuitry to reduce the time to achieve a lock condition. During a first mode, the frequency of a voltage controlled oscillator (VCO) is used to adjust the control voltage of the VCO to achieve a coarse lock condition. During a second mode, a reference frequency is used to control a charge pump to more precisely adjust the control voltage to achieve fine lock of the PLL. Because the VCO frequency is significantly higher than the reference frequency, the control voltage is varied at a greater rate during the first mode. In some embodiments, the time to achieve lock may be further reduced by initializing the VCO control voltage to a particular voltage so as to reduce the difference between the control voltage at start-up and the control voltage at the beginning of the first mode during coarse lock.
