Abstract
In a high frequency mode a multiphase voltage-controlled oscillator (VCO) generates a first plurality of signals where each has the desired frequency and a different phase. A phase interpolator generates the signal at the desired frequency and the desired phase using a first plurality of signals. In a low frequency mode the VCO generates a second plurality of signals where each has a frequency which is a multiple of the desired frequency and a different phase. A multiphase frequency divider generates a third plurality of signals by dividing the frequency of the second plurality to the desired frequency while maintaining a phase relationship with the second plurality of signals. The phase interpolator generates the signal at the desired frequency and the desired phase using the third plurality.
