ABSTRACT:
An embodiment of a communication system is provided, in which a high frequency oscillator generates a first high frequency signal upon receipt of no disable signal. The first high frequency signal is commonly shared by at least two modules. Each module coupled to the high frequency oscillator operates in either busy or idle mode, wherein the module operates at the first high frequency signal when in busy mode, and asserts a request signal when in idle mode. A disablement unit, coupled to the first and second modules, asserts the disable signal to the high frequency oscillator when all of the request signals are asserted, thereby forcing the high frequency oscillator to cease the generation of the first high frequency signal.
