Abstract
The present invention discloses an electronic apparatus. The electronic apparatus comprises a reference oscillator, for generating a reference clock; a first communications module, comprising a first auto frequency control unit, for detecting a first frequency offset between the first communications module and a first communication device and generating a first detecting result; and a first frequency synthesizer, for adjusting the reference clock according to the first detecting result, to generate a first baseband clock; and a second communications module, comprising a second auto frequency control unit, for detecting a second frequency offset between the second communications module and a second communication device and generating a second detecting result; a second frequency synthesizer, for receiving and outputting the first baseband clock; and a compensation unit, for adjusting the first baseband clock according to the first detecting result and the second detecting result, to generate a second baseband clock.
