General Description
The RDA5820 is a single-chip broadcast FM transceiver with fully integrated synthesizer, IF selectivity and MPX decoder. The chip uses the CMOS process, support multi-interface and require the least external component. The package size is 4X4mm and is completely adjustment-free. All these make it very suitable for portable devices.
The RDA5820 has a powerful low-IF digital audio processor, this make it have optimum sound quality with varying reception conditions.
The RDA5820 use RDA patented dual synthesizers, all digital transmit structure, this make it have perfectly transmition performance and agility.
The RDA5820 support 65M~115M frequency band receive and transmit, integrate 4K memory, these make it can be used in simple wireless control appliance such as toy.Features
