Abstract
An integrated circuit to synchronize a pulse signal from a first clock domain to a second clock domain includes a first flip-flop and a second flip-flop. The first flip-flop has a first stage input, a first clock input, and a first stage output. The first clock input is driven by a first clock signal of the first clock domain, and the first stage input is driven by a result of XOR-ing the input pulse signal and the first stage output. The second flip-flop has a second stage input, a second clock input, and a second stage output. The second clock input is driven by a second clock signal of the second clock domain, and the second stage input is driven by the first stage output. The synchronized output pulse signal is generated by XOR-ing the second stage output with the first stage output.
