<p>A multi-mode terminal and a handover method for a multi-mode terminal. The multi-mode terminal comprises: a power source management chip, a digital baseband chip, a first radio frequency chip, a second radio frequency chip, a first card slot, a second card slot, a first clock source, and a second clock source. The power source management chip is connected to the digital baseband chip, the first card slot, and the second card slot. The digital baseband chip is further connected to the first card slot and the second card slot, and is connected to the first radio frequency chip and the second radio frequency chip through an in-phase/orthogonal I/Q data line and a control line, respectively. The first clock source is connected to the first radio frequency chip and provides a reference clock to the first radio frequency chip. The second clock source is connected to the second radio frequency chip and provides a reference clock to the second radio frequency chip. A clock path is further connected between the first radio frequency chip and the second radio frequency chip. The first radio frequency chip provides an output clock to the second radio frequency chip through the clock path to serve as the reference clock for the second radio frequency chip.</p> |
