1 / 29 page Ordering number : ENN6871A 92001TN (OT) No. 6871-1/29 Overview The LC72714W is data demodulator ICs for receiving FM multiplex broadcasts for mobile reception in the DARC format. This IC includes an on-chip bandpass filter for extracting the DARC signal from the FM baseband signal. It also integrates a decoder circuit that performs the VICS data processing on the same chip and can implement a compact, multifunction VICS reception system. The LC72714W is an improved version of the LC72710W that features circuit improvements that allow a single tuner to receive both the VICS data and the dGPS data supported by the earlier device. Note that a contract with VICS Center is required to evaluate this sample IC and to produce end products that support VICS. Functions • Adjustment-free 76 kHz SCF bandpass filter • Built-in VICS decoder • MSK delay detection system based on a 1T delay. • Error correction function based on a 2T delay (in the MSK detection stage) • Digital PLL based clock regeneration function • Shift-register 1T and 2T delay circuits • Block and frame synchronization detection circuits • Functions for setting the number of allowable BIC errors and the number of synchronization protection operations. • Error correction using (272, 190) codes • Built-in layer 4 CRC code checking circuit • On-chip frame memory and memory control circuit for vertical correction • 7.2 MHz crystal oscillator circuit • Two power saving modes: STNBY and EC STOP • Dedicated frame synchronization circuit for simultaneous reception of dGPS and VICS data • Applications can use either a parallel CPU interface (DMA) or a CCB serial interface. • Supply voltage: 2.7 to 3.6 V Package Dimensions unit: mm 3190-SQFP64 1.25 0.5 1.25 0.18 12.0 116 17 32 33 48 49 64 10.0 0.5 0.5 0.15 SANYO: SQFP64 [LC72714W] LC72714W SANYO Electric Co.,Ltd.
