Abstract
A method of performing a frequency scan at a radio includes placing the radio in an active mode and, while maintaining the radio in the active mode, for each of a plurality of target frequencies determining a coarse frequency tuning value based on the target frequency. The radio places a phase locked loop (PLL) in an open-loop configuration and while the PLL is in the open-loop configuration, programs the VCO with the coarse frequency tuning value. The radio programs the divider with a feedback adjustment based on the target frequency, places the PLL in a closed-loop configuration, and in response to the PLL reaching a settled state, performs an operation based on an output signal of the PLL.
