    Abstract: Systems and methods are disclosed to provide static and/or dynamic phase adjustments to a data signal relative to a clock signal. For example, the data signal may be delayed by a coarse delay and/or a fine delay to match the timing of the clock signal independently for each input path (e.g., per input pad). The delay may be as a function of positive and/or negative clock edges.

    Abstract: A source synchronous interface determines an amount of delay for an incoming data signal and a phase offset for a latch device that latches the incoming data signal. A delay locked loop may be a dual loop delay locked loop, in which case, the loops may use a low jitter, local clock signal and an input clock signal that was transmitted with the data signal. The low jitter, local clock signal may provide a stable source from which to derive good clock signal edge transitions. The input clock signal may be used to determine the long term clock signal drift. A finite state machine within the dual loop delay locked loop may provide the necessary information for the amount of delay and the phase offset. The delay of the incoming data signal is produced by an analog or digital delay line.
