Abstract
Methods and apparatus implementing techniques for prevention of metastability in a bistable circuit. The techniques include detecting a change in a data signal, sampling the detected change in reference to a sampling window of a clock signal input of a bistable circuit to determine if the detected change occurs within the sampling window, and selecting a stable data input to present to an input of the bistable circuit based on whether the detected change occurs within the sampling window. The sampling window represents a time period during which a change in the data signal can cause metastability in a bistable circuit.
