Asynchronous frequency divider for phase detent loop, has asynchronous finite state machine that is designed to cyclically pass through stable states in respective operating modes, where stable state is subset of other stable state

摘要

The divider has an asynchronous finite state machine (120), which is switched between two operating modes, where the divider exhibits respective division ratios in the respective modes. An output variable is made available in the output of the state machine. The machine is designed to cyclically pass through the stable states in the respective operating modes, where one of the stable states is a subset of the other stable state.
