Abstract
A phase alignment system for aligning clocks is disclosed. The system includes a calibration circuit and a phase locked loop (PLL). The calibration circuit is configured to receive a variable clock and a reference clock; determine phase alignment based on metastability; determine phase misalignment and generate a phase shift upon determining phase misalignment. The PLL is configured to generate the variable clock and incorporate the phase shift.
