Abstract
An apparatus and a method for acquiring synchronization to support multi-frequency in a mobile communication terminal are provided. The apparatus includes a frequency generator, a control signal generator and at least two modems for operating respective Frequency Allocations (FAs) by sharing the frequency generator and the control signal generator. In an embodiment, the frequency generator respectively receives first reference frequency clock signals from an oscillator of each of the at least two modems and generates a second reference frequency clock signal and the control signal generator outputs a signal for controlling the oscillator of each of the at least two modems according to a frequency offset value estimated in each of the at least two modems.
