asynchronous circuit Asynchronous circuit (clockless or self-timed circuit) is a sequential digital logic circuit that does not use a global clock circuit or signal generator to synchronize its components. Instead, the components are driven by a handshaking circuit ...
s. There are also electronic digital circuits called ''synchronizers'' that attempt to perform arbitration in one clock cycle. Synchronizers, unlike arbiters, are prone to failure. (See
metastability in electronics In electronics, metastability is the ability of a digital electronic system to persist for an unbounded time in an unstable equilibrium or metastable state. In digital logic circuits, a digital signal is required to be within certain voltag ...

, whenever there is signal transfer between two systems operating at different frequencies or same frequency with different phases, synchronizer block is used as an interface so that signal from transmitter block is reliably interpreted by the receiver. The block usually uses metastable hardened flops offering single or double latency delays at the output. This block ensures that there is no
metastability In chemistry and physics, metastability denotes an intermediate Energy level, energetic state within a dynamical system other than the system's ground state, state of least energy. A ball resting in a hollow on a slope is a simple example of me ...
