ABSTRACT:
Some embodiments include a delay line configured to apply a delay to an input signal to provide an output signal; an input circuit configured to provide the input signal based on a first signal, such that the cycle time of the input signal is different from a cycle time of the first signal; an output circuit configured to provide a second signal based on the output signal, the second signal having a cycle time different from a cycle time of the output signal; and a controller configured to adjust the delay to control a timing relationship between the first signal and the second signal. Other embodiments are described and claimed.
