Abstract
A method for operating a wireless communications device having a low energy mode of operation and a second mode of operation includes providing a first clock signal and a second clock signal in the second mode of operation. The first clock signal has a first frequency within a first frequency offset range. The second clock signal has a second frequency within a second frequency offset range. The first frequency is lower than the second frequency, and the first frequency offset range is greater than the second frequency offset range. The method includes generating a calibrated version of the first clock signal in the second mode of operation using a measurement of the first clock signal measured using a timer controlled by the second clock signal. The method includes using the calibrated version of the first clock signal in the low energy mode while the second clock signal is disabled.
