Switching circuit and method thereof for dynamically switching host clock signals
A switching circuit located in a computer system is disclosed in the present invention. The switching circuit comprises a first phase-locked loop generating a first host clock signal, a second phase-locked loop generating a second host clock signal and an output switch unit coupled to the first PLL and the second PLL. When the computer system operates in a first mode, the output switch unit chooses the first host clock signal to be a fundamental clock signal of the front side bus. In the other hand, when the computer system operates in a second mode, the output switch unit chooses the second host clock signal to be a fundamental clock signal of the front side bus.
