Abstract
A mobile radio communications device has a first crystal oscillator for providing a first master clock frequency for the timebase of a first communications system, a second crystal oscillator for providing a second master clock frequency for the timebase of a second communications system, and a phase locked loop connected between the first and second crystal oscillators and arranged to lock the first and second crystal oscillators together so that the two timebases cannot drift.
