RDA5807M
SINGLE-CHIP BROADCAST FM RADIO TUNER
1 General Description The RDA5807M 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. All these make it
very suitable for portable devices.
The RDA5807M series has a powerful low-IF digital audio
processor, this make it have optimum sound quality with
varying reception conditions.
The RDA5807M series support frequency range is from
50MHz to 115MHz. 1.1 1 GND LOUT 10 2 FMIN ROUT 9 3 GND RDA5807M GND 8 4 SCLK VDD 7 5 SDIO RCLK 6 Figure1-1.
