An apparatus and a method are disclosed for synchronizing clock signals distributed within a wireless device. In some embodiments, a local oscillator (LO) clock signal is buffered and distributed to two or more transceivers within the wireless device. Each transceiver may include a configurable clock divider to divide the distributed LO clock signal and generate an output clock signal. A phase detector compares output clock signals from each of the configurable clock dividers and generates an output signal in accordance with a determined phase difference. The phase detector output signal may cause at least one of the configurable clock dividers to modify its respective output clock signal, and thereby synchronize output clock signals between different configurable clock dividers. In some embodiments, a clock signal from a configurable clock divider may be modified (shifted) by approximately 90 or 180 degrees.
