Overview

The LC72711LW is a data demodulator IC 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 LC72711LW support both parallel and 'computer control bus' serial CPU interfaces.

Adjustment-free 76 kHz SCF bandpass filter
Supports all FM multiplex frame structures 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
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
Applications can use either a parallel CPU interface (DMA) or a 'computer control bus' serial interface.
Supply voltage: 2.7 to 3.6 V
