A semiconductor integrated circuit device includes a clock generation unit, a signal processing unit, an FM receiving unit, a processor, and a bus. The signal processing unit, FM receiving unit, and processor operate in synchronization with the clock generated by the clock generation unit. The FM receiving unit includes an RF unit, a canceller and a wave detector. The RF unit performs frequency conversion of the received FM signal using the clock as a base signal. The canceller produces a replica of a noise using a signal as a reference signal to cancel the noise on the FM signal. The signal is obtained by performing frequency conversion of a signal in at least one of the signal processing unit and the bus using the clock as a base signal. The wave detector detects the FM signal in which the noise is cancelled.
