The RDA5807FP series is the newest generation
single-chip broadcast FM stereo radio tuner with fully
integrated synthesizer, IF selectivity, RDS/RBDS and
MPX decoder. The tuner uses the CMOS process,
support multi-interface and require the least external
component. The package sizes is SOP16. It is
completely adjustment-free. All these make it very
suitable for portable devices.
The RDA5807FP series has a powerful low-IF digital
audio processor, this make it have optimum sound
quality with varying reception conditions.
