Description
The RDA5802NE is a single-chip broadcast FM transceiver with a fully integrated synthesizer, IF selectivity, and MPX decoder. This IC chip is a product category that uses the CMOS process, supports multi-interface, and requires few external components. It is completely adjustment-free and has a package size of 4X4mm. All of these qualities make the RDA5802NE perfect for portable devices. Additionally, the RDA5802NE has a powerful low-IF digital audio processor that provides optimum sound quality, even with varying reception conditions. The RDA5802NE uses RDA patented dual synthesizers and an all-digital transmit structure for perfect transmission performance and agility. It supports 65M~115M frequency band receive and transmit, integrates 4K memory, and can be used in simple wireless control appliances such as toys.
