LC72717PW Mobile FM Multiplex Broadcast (DARC) Receiver

LC72717PW Mobile FM Multiplex Broadcast (DARC) Receiver IC Overview The LC72717PW is a data demodulation LSI for receiving FM multiplex broadcasts for mobile reception in the DARC format. This LSI includes an on-chip bandpass filter for extracting the DARC signal from the FM baseband signal. It also supports ITU-R recommended FM multiplex frame structures (.
