Abstract

Aspects of the disclosure provide for an apparatus. In an example, the apparatus includes a clock switching circuit coupled to oscillators and one or more circuit units. The clock switching circuit is configured to receive, from the oscillators, a set of frequency signals, provide an uplink primary clock signal and an enable signal to the one or more circuit units, the enable signal determined synchronously with the uplink primary clock signal, receive, from the one or more circuit units or a clock management circuit, a clock frequency request, provide the uplink primary clock signal based on a first signal of the set of frequency signals, and according to the clock frequency request, determining whether to continue to provide the uplink primary clock signal based on the first signal or on a second signal of the set of frequency signals.
