Abstract
Disclosed is an apparatus for generating a stable clock signal having a Long term jitter noise removed therefrom. In a mobile communication terminal having a power management chip for converting a sinusoidal wave oscillated in a crystal into a clock signal of square wave, the sinusoidal wave is converted into a square wave clock signal by the stabilized driving power having no alternating current components, and thus a power noise of the square wave clock signal is removed. Then, the square wave clock signal having the power noise removed therefrom is outputted after a predetermined delay time. Accordingly, it is possible to supply the clock signal having the Long term jitter noise removed therefrom and synchronized to each device in the mobile communication terminal.
