SINGLE-CHIP BROADCAST FM RADIO TUNER
Rev.1.7Jun.2009
1 General Description
The RDA5802E (RDA5802 Enhanced) is a
single-chip broadcast FM stereo radio tuner with
fully integrated synthesizer, IF selectivity and MPX
decoder. The tuner uses the CMOS process,
support multi-interface and require the least
external component. The package size is 4X4mm
and is completely adjustment-free. All these make
it very suitable for portable devices.
The RDA5802E has a powerful low-IF digital audio
processor, this make it have optimum sound quality
with varying reception conditions.
The RDA5802E can be tuned to the worldwide
frequency band.
