Abstract
An integrated circuit has an oscillator circuit having an on-chip oscillator, a digital phase locked loop and a sensor. A frequency of an output signal from the oscillator circuit is adjustable. The digital phase locked loop receives the output signal from the oscillator circuit at an input and a synchronization signal based on an output signal from an external precision oscillator in the form of a crystal oscillator or MEMS oscillator at an external interface and generates a control signal in order to synchronize the frequency of the oscillator circuit with the frequency of the external crystal oscillator. The sensor is designed to measure at least one environmental parameter, wherein the digital phase locked loop is designed to take into account the at least one measured environmental parameter when generating the control signal.
