摘要:
A phase locked loop (PLL) which includes a phase frequency detector coupled with a time to digital converter capable of comparing a reference signal with an oscillator signal and generating a digital value representing the phase difference between the reference signal and the oscillator signal. The PLL further includes a state machine for phase acquisition that is capable of generating a control value depending on the digital value, and a controllable oscillator that is capable of generating the oscillator signal depending on the control value.
