An apparatus for synchronizing a signal from a first clock domain into a second clock domain is disclosed. The apparatus may include circuitry, a synchronization circuit, and a clock gate circuit. The circuitry may de-assert a first enable signal dependent upon a first clock signal. The synchronization circuit may generate a second enable signal synchronized to a second clock signal and may de-assert the second enable signal in response to de-asserting the first enable signal. The clock gate circuit may generate a third clock signal dependent upon the second clock signal, and may disable the third clock signal responsive to de-asserting the second enable signal. The circuitry may further disable the second clock signal in response to determining a predetermined period of time has elapsed since de-asserting the first enable signal.
