Abstract: An electronic device comprising one or more subcircuits configured to receive a clock signal, the clock signal configured to switch from a reference clock signal to a second clock signal based on a clock bypass signal, a timer configured to receive the reference clock signal and output an alignment signal based on the reference clock signal, wherein a frequency of the alignment signal is determined based on clock frequencies of the one or more subcircuits; a clock alignment module coupled to the timer and the one or more subcircuits and configured to receive the clock bypass signal, determine that the clock bypass signal has changed to switch the one or more subcircuits to the reference clock signal from the second clock signal, block the clock signal from being received by the one or more subcircuits, receive the alignment signal, and unblock the clock signal based on the alignment signal.
