Abstract:
1. A method for reducing effects of spurious frequencies in a wireless communications device, the method comprising: powering up the wireless communications device in a first mode of operation comprising one of an analog mode and a digital mode, the first mode of operation corresponding to a first passband frequency range of a plurality of selectable passband frequency ranges; operating a processor in a default processor clock frequency of a plurality of processor clock frequencies, the default processor clock frequency corresponding to a second mode of operation comprising the other of the analog mode and the digital mode; determining that the default processor clock frequency produces spurious signals in the first passband frequency range; switching to a first processor clock frequency of the plurality of processor clock frequencies that produces no substantial spurious signals in the first mode of operation; and maintaining the first processor clock frequency as song as the wireless communications device operates in the first mode of operation.
