Mobile FM Multiplex Broadcast Receiver IC with Built-in VICS Decoder

LC72713W

Overview

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.

Functions

■Adjustment-free SCF based 76 kHz bandpass filter

■VICS decoder circuit

■MSK delay detection circuit using a 1T delay

■Error correction function using a 2T delay (in the MSK detection stage)

■Digital PLL based clock regeneration circuit

■Shift register type 1T and 2T delay circuits

■Block and frame synchronization detection circuits

■Function for setting the allowable BIC error count and synchronization protection count

■Error correction using (272,190) codes

■Layer 4 CRC code checking circuit

■Includes the frame memory and memory control circuit required for vertical correction

■7.2 MHz crystal oscillator circuit

■Two power saving modes (standby and EC stop modes)

■Dedicated frame synchronization circuit optimal for simultaneous reception of dGPS and VICS data

■Either a CPU parallel interface (DMA) or a CCB serial interface can be used

■ Supply voltage: 4.5 to 5.5 V

■ Package: SQFP64 (10 10 mm)

The DARC (Data Radio Channel) FM multiplex broadcast technology was developed by NHK

(Japan Broadcasting Corporation). DARC is a registered trademark of NHK Engineering Services, Inc. (NHK-ES).

A separate contract with NHK-ES is required for the manufacturer or sale of electronic equipment that uses DARC technology.
