Abstract
Providing clock signals includes receiving a first clock signal at a first clock circuit and at a second clock circuit, where the first clock signal comprises first cycles. A second clock signal is generated from the first clock signal at the first clock circuit, where the second clock signal comprises second cycles and a first cycle corresponds to a first multiple of the second cycles. A third clock signal is generated from the first clock signal at the second clock circuit, where the third clock signal comprises third cycles and a second cycle corresponds to a second multiple of the third cycles. The first clock signal and the second clock signal are sampled using the third clock signal. A safe cycle is determined in response to the sampled clock signals. Data is transferred in accordance with the safe cycle.
