    摘要： An integrated multi-mode radio transmitter includes a multiplexor and a shared front-end. The is operable to select an IF signal of a plurality of IF signals based upon a selection signal that is indicative of a particular operational mode of the one of the plurality of IF signals. The shared front-end is coupled to receive the selected IF signal, wherein the shared front-end converts the selected IF signal into a radio frequency (RF) signal that is modulated in accordance with the particular operational mode of the one of the plurality of IF stages.

    摘要： A method and system sharing a Bluetooth processor for FM functions are provided. The single chip may comprise an integrated Bluetooth radio, an integrated FM radio, and processor system. A processor in the processor system may be utilized for Bluetooth and FM data processing and may time multiplex between the Bluetooth and FM data processing based on interrupt signals. The processor may operate in a low power mode based on a clock signal generated from a low power oscillator. When a Bluetooth interrupt signal is received, the processor may enable Bluetooth data processing that may be based on a Bluetooth clock signal. When an FM interrupt signal is received, the processor may enable FM data processing that may be based on an FM clock signal. When data processing is complete, the processor may return to the low power mode operation.
