The LC72709W is a data demodulation IC for receiving FM multiplex broadcasts for mobile receivers in the DARC format. This IC includes a built-in bandpass filter that extracts the DARC signal from the FM baseband signal. Since this IC supports all of the FM multiplex broadcast frame structures (methods A, A', B, and C) from the ITU-R recommendations, it is optimal for use in radios for worldwide use that support FM multiplex reception.
