A circuit includes a resonator, a transistor pair, and a common-mode feedback circuit. The transistor pair is cross-coupled across the resonator. The common-mode feedback circuit is coupled to the transistor pair. The common-mode feedback circuit includes first and second degeneration cells. The second degeneration cell is connected in parallel with the first degeneration cell. The second degeneration cell is configured to switchably vary a current flow through the transistor pair.

In an example, a system is adapted to be coupled to a load device having a load clock. The system includes a clock generation device with a pin. The system also includes a capture circuit coupled to the pin and operable to sample a value at the pin. The system includes a D flip-flop having a data input coupled to the capture circuit, a clock input coupled to a clock, and having an output, where the D flip-flop is operable to provide, at the output, a system reference event (SYSREF) signal to align the load clock to the clock, based at least in part on the value at the pin.
