摘要
A semiconductor IC includes an analog audio input circuit, a selecting unit, and an audio processing circuit, which maybe a car navigation chip. The analog audio input circuit includes an RF module and at least one analog audio input module, respectively for providing a first analog audio input signal and at least one second analog audio input signal. The RF module includes an FM/AM broadcast receiving function. The selecting unit is coupled to the RF module and analog audio input module, and outputs a target analog audio input signal according to the first and second analog audio input signals. The audio processing circuit is coupled to the selecting unit, and performs an audio signal process upon the target analog audio signal to generate an audio output signal.
