摘要:
A device for adjusting the timing of at least one edge of an output pulse created in response to a reference pulse is disclosed. Such a device may include a first memory circuit having two or more first memory cells and a second memory circuit also having two or more second memory cells. The first memory circuit may be configured to periodically sample the reference pulse at the rising edges of a first sample clock while the second memory circuit may be configured to periodically sample the reference pulse at the falling edges of the first sample clock. A combinatorial logic circuit may also be included to produce the output pulse having at least one adjusted edge based on a set of timing instructions and timing information provided by the first and/or second memory circuits.
