LC72711LW

Ordering number : ENN6167 CMOS IC LC72711W, 72711LW Mobile FM Multiplex Broadcast (DARC) Receiver IC Overview The LC72711W and LC72711LW are data demodulator ICs for receiving FM multiplex broadcasts for mobile reception in the DARC format. This IC includes an onchip bandpass filter for extracting the DARC signal from the FM baseband signal. Furthermore, since this IC supports all of the IT-R recommended FM multiplex frame structures (methods A, A', B, and C), it is optimal for worldwide market radios that provide FM multiplex reception. The LC72711W and LC72711LW support both parallel and CCB serial CPU interfaces. 7.2 MHz crystal oscillator circuit Two power saving modes: STNBY and EC_STOP Applications can use either a parallel CPU interface (DMA) or a CCB serial interface. Supply voltage: 4.5 to 5.5 V (LC72711W), 2.7 to 3.6 V (LC72711LW) Package Dimensions unit: mm 3190-SQFP64 [LC72711W, 72711LW] Functions Adjustment-free 76 kHz SCF bandpass filter Supports all FM multiplex frame structures (methods A, A', B, and C) under CPU control. 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 ...
