Abstract:
A method and device are disclosed. In one embodiment the method includes driving a first clock domain reference signal on a first clock tree and driving a second clock domain reference signal on a second clock tree. The first tree routes the first signal from a PLL to a first clock domain drop off circuit and the second tree routes the second signal from the PLL to a second clock domain drop off circuit. A jitter produced from the second tree is less than a jitter produced from the first tree. The method continues by detecting any phase misalignment between the first signal and the second signal. The method also causes the first signal to be delayed so that it aligns with the second signal.
