Abstract: Embodiments of an integrated circuit (IC) comprising frequency change detection circuitry are described. Some embodiments include first circuitry to generate a second clock signal based on a first clock signal, wherein the first clock signal has a first clock frequency, and wherein the second clock signal has a second clock frequency that is an integral multiple of the first clock frequency. The embodiments further include second circuitry to obtain samples by oversampling the first clock signal using the second clock signal. Additionally, the embodiments include third circuitry to detect a change in the first clock frequency based on the samples.
