Abstract
Systems, methods and media for a fast locking phase locked loop (FLPLL) are disclosed. A FLPLL apparatus can include a voltage controlled oscillator (VCO) coupled to a phase frequency detector and can also include a frequency divider as part of a feedback loop. The VCO can accept a pull up voltage and a control signal from the phase frequency detector and provide an output clock signal to circuits that need synchronization. Such a configuration can greatly reduce the time the PLL requires to go from a dormant state to a fully operational state. During this start up mode, a frequency detection module can be utilized to detect an output frequency of the voltage controlled oscillator and when the VCO output frequency is not as high as a reference frequency, the frequency detection module can disabled the feedback loop during this start-up mode.
