Product Summary
The LC72711LW-E is a mobile FM multiplex broadcast DARC receiver. 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, B, and C), it is optimal for worldwide market radios that provide FM multiplex reception.
