Abstract: Aspects of this disclosure relate to adjusting a phase of a clock signal provided to a device based on a feedback signal from the device. The feedback signal can provide phase information associated with the device and/or other information associated with the device, such as temperature information. A feedback signal processor can compute a phase control signal based on the feedback signal. The phase control signal can be used to adjust the phase of the clock signal. By adjusting the phase of one or more clock signals, several devices, such as data converters, can be synchronized.

Abstract: Aspects of this disclosure relate to reference switchover. In one embodiment, an apparatus includes a phase error detector, a phase alignment detector, and a selection circuit. The phase error detector is configured to generate an indication of a relative phase difference between a first reference clock signal and a second reference clock signal. The phase alignment detector is configured to receive the indication of the relative phase difference and determine when the relative phase difference satisfies a preset threshold. The selection circuit is configured to transition from providing the first reference clock signal as a clock system reference signal to providing the second reference clock signal as the clock system reference signal responsive to the phase alignment detector detecting that the relative phase difference satisfies the preset threshold.
