Abstract:
A method of retrieving data transmitted over a communications channel, the method comprising:providing a Delay Locked Loop (DLL); generating a first plurality of unreferenced master phases using the DLL; mapping the unreferenced phases into named phases to reference the named phases to word boundaries of the data transmitted; generating a first plurality of local phases, including center-data phases and edge-data phases that correspond to data-bit centers and data-bit edges for each of a second plurality of bits transmitted per major channel clock period; dynamically adjusting a delay applied to the first plurality of local phases to establish a second plurality of local center-data phases in a center of the second plurality of bits received by a corresponding receiver; and serializing and de-serializing the channel data for the receiver using the center-data phases.
