Description:
"RRD-102V2.0" Stereo Radio Module (FM Stereo Radio Module) is High sensitivity, low power consumption, small size FM stereo radio module. 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. Adopt RDA5807M (or RDA5802NM) of RDA Microelectronics, this circuit has few peripheral components and extremely low noise figure. It has the advantages of small size, low power consumption, low cost, simple application and wide range of use. It is a single-chip FM stereo radio module that is easy to use and highly cost-effective.
It is suitable for integration into your designs innovative.
