RDA5807M
SINGLE-CHIP BROADCAST FM RADIO TUNER
Rev.1.0May.2011
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.
