Abstract

A synchronization circuit and a cascaded synchronization circuit for converting an asynchronous signal into at least one synchronous signal are provided. The synchronization circuit includes a signal control circuit, a flip-flop circuit, a clock enable circuit and a clock control circuit. The flip-flop circuit is coupled to the signal control circuit, the clock enable circuit is coupled to the signal control circuit and the flip-flop circuit, and the clock enable circuit is coupled to the signal control circuit and the flip-flop circuit. The signal control circuit and the clock control circuit can guarantee hold time and setup time is sufficient to allow the flip-flop circuit to output the synchronous signal without glitch regardless of the asynchronous signal.
