Abstract
A phase locked loop device includes a phase detector that measures a difference in phase between a reference clock signal and an output clock signal provided to a device module. The phase detector provides a pulse having a width indicative of the phase difference. If the phase difference exceeds one of a plurality of threshold values, an indicator can be asserted. Based on the indicator, a control module can take remedial action, such as providing a different clock signal to the device module or triggering an interrupt at a processor device.
