LC72715PW ^{Mobile FM Multiplex Broadcast IC}
with On-Chip VICS Decoder
Overview
The LC72715PW is a data demodulation LSI for receiving FM multiplex broadcasts for mobile reception in the DARC
format. This LSI includes an on-chip bandpass filter for extracting the DARC signal from the FM baseband signal. It
also integrates a decoder that performs the VICS data processing on the same chip and can implement a compact,
multifunction VICS reception system. LC72715PW is control-compatible with LC72714W and LC72710LW.
(Description of dGPS reception function has been deleted, because the dGPS service finished at the end of March 2008).
Note that a contract with the VICS Center is required to evaluate this LSI’s sample and to produce VICS compatible
products. It also requires a contract with the NHK Engineering Service to produce VICS compatible products.
Functions
• Adjustment-free 76kHz SCF bandpass filter
• Built-in VICS decoder
