Abstract
A phase-locked loop (PLL) comprising a multi-band oscillator and a memory configured to store control input for the oscillator. The PLL is operable in a calibration mode in which the PLL is configured to acquire a frequency controlled word (FCW) for the PLL corresponding to a frequency generated by the oscillator in response to a first control input threshold on a first band of the oscillator; generate a frequency corresponding to said FCW on a second band of the oscillator adjacent to said first band; identify a second control input causing the oscillator to generate said frequency corresponding to said FCW and store said second control input in memory.
