2 Description
AR1000/AR1010 is a highly integrated single chip stereo FM radio receiver for all kinds of
applications. AR1000/AR1010 supports worldwide FM bands from 76 to 108MHz. It
integrates LNA, Mixer, Oscillator and LDO regulator to minimize the external BOM cost. The
built-in FM signal processing unit with noise reduction mechanism provides optimum sound
quality. A simple 2-wire/3-wire interface allows easy control from the host. For AR1000, a
Radio Data System (RDS) and Radio Broadcast Data System (RBDS) demodulator and
decoder are also supported.
AR1000 and AR1010 are pin-to-pin compatible and are the same in all FM radio receiver
functions, specs and packages except the RDS/RBDS function. AR1000 supports RDS/RBDS
receiver function, while AR1010 do not.
