The highest integration level minimizes external BOM cost and provides optimum sound Radio ReceiverThe Radio Receiver part comprises a LNA, a Low-IF mixer and a VGA. The front-end gain of the LNA could be adjusted automatically and thus optimize the received signal-to-noise ratio. The RF signal is then converted to Low-IF band and amplified by the VGA, which is also automatically adjusted. After then the received signal is fed into the FM signal processing unit.

( , 32 KHz, , 12 MHz, 13 MHz, , 24 MHz, 26 Mhz, 27 MHz, ) FM signal processing UnitThe main function of the FM signal processing unit includes FM Demodulation and Stereo Decoding . The received FM signal at VGA output is first demodulated into stereo multiplexed signals (Left+Right and Left Right) and then decoded into Left and Right signals individually by the stereo decoder.

10 Two time constants (50 s or 75 s) of de-emphasis are provided and programmable through the serial decoded stereo signals are output to the LOUT and ROUT pins. The output volume could be adjusted or mute through the serial interface. The stereo output could be blocked and only mono signal is output under weak Serial 2-Wire InterfaceSerial 2-wire interfaces are provided to read and write the control 10 of 17 CONFIDENTIALC opyright 2009, Airoha Technology Single Chip FM RadioDatasheetVersion 27-Aug-2010AR1019 Single Chip FM Radio2-Wire Interface Read and Write Timing Parameters70%30%70%30%CLOCKDATATLOWTHIGH TIFTIRTPSTBUFTS1TH1TS2TH2TS3 TIRTIFTOFSTARTSTARTSTOP2-Wire Interface Read and Write ProcedureCLOCKDATASTARTA6~A0,R/WD15~D8D7 ~D0 STOPA ddress + R/WDataDataACKACKACKPage 11 of 17 CONFIDENTIALC opyright 2009.
