Abstract
A frequency synthesizer including frequency and phase locked loop that operates in either a frequency locked loop (FLL) mode or a phase locked loop (PLL) mode. In a first state, the frequency and phase locked loop operates in the FLL mode for initial frequency acquisition. Once the frequency and phase locked loop has locked in FLL mode, the frequency and phase locked loop transitions to the PLL mode for normal operation.
