According to an aspect of the present invention, one of multiple clock
signals of different relative phases is selected based on a desired delay
magnitude, and the digital values received on an input signal are then
synchronized to an edge ("first edge") of the selected clock signal to
provide the digital values with the desired delay magnitude. In an
embodiment, the selected clock signal can be delayed by a fine value
(less than the minimum phase difference of the multiple clock signals) to
provide a wide span of desired delays. An aspect of the invention
provides for a synchronization circuit with reduced latency and which is
substantially invariant to process, voltage and temperature (PVT)
changes.
