Abstract
A circuit includes a reference clock terminal configured to receive a signal indicative of a reference clock, multiple low power oscillators (LPOs) and a controller. Each LPO is operable in at least one of three states including a sleep state in which the LPO is powered off, a calibration state in which the LPO undergoes calibration and an active mode in which the LPO is configured to provide a real-time clock based on the reference clock. The controller controls operation of the LPOs such that at most a single LPO is in the active state at any given time.
