Abstract
Automatic dynamic phase alignment of digital data, skewed with respect to a local clock, is obtained over a wide range of skew and skew frequencies. The system includes (i) an edge detector (52) containing predetermined delays (e.g., D1, D2, D3), (ii) delay registers (e.g., 72, 76, 84, 86), and (iii) a controller (54) for deciding when un-delayed and delayed data D0, D1, D2, D3 have transitions (102-138) which bracket corresponding clock transitions (100, 110, 120, 130) and regulating a subsequent two-stream parallel (e.g., bi-phase) register-multiplexer (56). The controller selects from the register-multiplexer (56), whichever of in-phase data D or delayed data DD has its transition spaced away from the clock transition by at least one delay D1, D2, or D3.
