摘要： Systems and methods are provided for providing precision timing signals. A first register bank, driven by a first clock signal, provides a first delay along a first signal path. A second register bank, driven by a second clock signal related to the first clock signal, provides a second delay along a second signal path. A system control controls at least one of the first and second banks of registers to control the first and second delays, as to provide a desired skew between the output of the first signal path and the second signal path.
