    Abstract: An apparatus comprising a frequency monitor circuitry to receive a first clock signal, a second clock signal and an expected frequency ratio, determine whether a ratio between the first clock signal and the second clock signal matches an expected an expected frequency ratio and generate an error signal upon a determination that the ratio between the first clock signal and the second clock signal does not match the expected frequency ratio.

    Abstract: Techniques and mechanisms for determining an amount of skew between two clock signals. In an embodiment, detector circuitry receives a first signal and a signal which indicate (respectively) a NAND combination of clock signals, and a NOR combination of the clock signals. The detector circuitry evaluates a first length of time that the first signal indicates a respective first logic state, and a second length of time that the second signal indicates a respective second logic state. The skew is calculated based on a difference between the first length of time and the second length of time. In another embodiment, one of the first signal or the second signal is generated with a combinatorial logic gate, a transistor of which is relatively large, as compared to another transistor which is to operate based on one of the first signal, the second signal, or the clock signals.
