Each Stratix II GX receiver channel features a DPA block for phase
detection and selection, a SERDES, a synchronizer, and a data realigner
circuit. You can bypass the dynamic phase aligner without affecting the
basic source-synchronous operation of the channel. In addition, you can
dynamically switch between using the DPA block or bypassing the block
via a control signal from the logic array.
