RDA5807FP
SINGLE-CHIP BROADCAST FM RADIO TUNER
1 Rev.1.2-April.2012 General Description 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. 1 GPIO1 GPIO2 16 2 GND GPIO3 15 3 RF GND GND 14 4 FMIN LOUT 13 RDA5807FP 5 GND ROUT 12 6 GND GND 11 7 SCLK VDD 10 8 SDA RCLK 9 The RDA5807FP series support frequency range is from 50MHz toFigure1-1.
