System for synchronizing operation of a circuit with a control signal, and corresponding integrated circuit

摘要

A system for synchronizing the operation of a circuit with a control signal includes synchronization flip-flops operating in cascade for receiving a control signal to be synchronized and providing a corresponding control signal synchronized with a clock signal, and a circuit including a finite state machine for receiving the clock signal having state flip-flops for storing the current state of the finite state machine, wherein a last synchronization flip-flop includes one of the state flip-flops.
