Abstract
A digital data buffer has at least one data path and a parallel reference data path. The data path includes a first and second data register, and the reference path includes a third data register. A learn cycle control signal is applied to a multiplexer for selecting between the data path and the reference data path and is also applied in parallel to control circuitry of a phase aligner. The learn cycle control signal is for adjusting the phase of a clock signal at a second clock output of a phase locked loop so as to optimize setup and/or hold timing at the data input of the second data register.
