RDA5802HS
SINGLE-CHIP BROADCAST FM RADIO TUNER Rev.1.1–Aug.2010
1 General Description
The RDA5802HS is a new generation 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 3X3 mm
and is completely adjustment-free. All these make
it very suitable for portable devices.
The RDA5802HS has a powerful low-IF digital
audio processor, this make it have optimum sound
quality with varying reception conditions.
The RDA5802HS can be tuned to the worldwide
frequency band, even support frequency range
50~65MHz.
