Abstract: Embodiments disclosed herein relate to the management of a multi-trim oscillator to provide synchronization across multiple frequencies derived from the multi-trim oscillator without causing spurious pulses of clock output. In one example, a system provides a first clock signal via an oscillator and a second clock signal based on the first clock signal and a divider. The system further receives a first signal that indicates a change in a frequency of the first clock signal from a first frequency to a second frequency. In response to the first signal, the system determines an edge of the second clock signal and provides, at a time based on the edge of the second clock signal, a second signal to the oscillator to cause the change to the second frequency.

Abstract: A clock generator system includes a first clock generator circuit to generate a first clock output signal having a first clock output frequency that is within a first bounded range of frequencies. The first clock generator circuit, during a transition mode, exhibits a first ramping of the first clock output signal from the first clock output frequency towards a target frequency. The system includes a second clock generator circuit to generate a second clock output signal having a second clock output frequency that is within a second bounded range of frequencies. The second clock generator circuit, during the transition mode, exhibits a second ramping of the second clock output signal from a second frequency towards the target frequency. A controller coupled to the first clock generator circuit and the second clock generator circuit selectively passes one of the first clock output signal or the second clock output signal as a system clock output signal.

Abstract: An acoustic transformer in a transmitter chain is disclosed. In one aspect, a differential power amplifier may produce a differential signal that is provided to a first transformer. A differential output of this first transformer is provided to an acoustic transformer that provides a single ended output signal for use by an acoustic filter. By making the second transformer an acoustic transformer, the second transformer may be integrated into the same circuitry that forms the acoustic filter, thereby simplifying the die. Further, the acoustic transformer may be tuned if ferroelectric resonators are used, which provides strong out-of-band signal cancelation.
