The LC72713W is a data demodulation IC for the reception of mobile FM multiplex broadcasts in the DARC
system.
The LC72713W includes a bandpass filter for the extraction of the DARC signal from the FM baseband.
This IC also includes a data circuit for processing VICS data and can implement a compact and highly functional
VICS reception system. The LC72713W features improvements over the circuits included in the LC72710W for
receiving VICS data and dGPS data in a single tuner.
Note that a separate contract with Vehicle Information and Communication Center is required for sample
evaluation of this IC and to manufacture VICS products.
