Description
The RDA5820 is a single-chip broadcast FM transceiver with a fully integrated synthesizer, IF selectivity and MPX decoder. This CMOS single-chip, fully-integrated FM transceiver supports multi-interface, requires the least external component, and is completely adjustment-free. It has a package size of 4X4mm, making it very suitable for portable devices. Furthermore, it has a low-IF digital audio processor, providing optimal sound quality under varying reception conditions. The RDA5820 has patented dual synthesizers, an all-digital transmit structure, making it capable of perfect transmission performance and agility. It supports the 65M~115M frequency band, integrates 4K memory, and can be used in simple wireless control appliances such as toys.
