An integrated circuit device includes at least a functional module arranged to receive a reference clock signal; a gating component configurable to perform gating of the reference clock signal; and a synchronization module. The synchronization module includes a trigger component arranged to receive a request for the functional module, the request being asynchronous with the reference clock signal, and to set an enable signal for the functional module in response to receiving the request therefor; and a synchronization component arranged to receive the enable signal, and in response to the enable signal being set to: configure the gating component to un-gate the reference clock signal; and synchronize an initial clock cycle of the reference clock signal received by the functional module following the reference clock signal being un-gated. |
