Abstract
A phase locked loop (PLL) provides output signals at multiple frequencies. In particular, the PLL includes a phase detector and two voltage controlled oscillators (VCOs). One of the VCOs is selectively enabled depending on a desired output signal. The phase detector receives a reference signal and a feedback signal from the enabled one of the two VCOs. The phase detector outputs a control signal that controls the VCO that provided the feedback signal.
