Description
The RDA5875Y is a single-chip broadcast FM transceiver with fully integrated synthesizer, IF selectivity and MPX decoder. It uses the CMOS process, supporting multi-interface, and requiring the least external component. The package size is 4X4mm and is completely adjustment-free. This makes it very suitable for portable devices. The RDA5875Y has a powerful low-IF digital audio processor, which makes it have optimum sound quality with varying reception conditions. The RDA5875Y uses RDA patented dual synthesizers, all-digital transmit structure, making it have perfectly transmission performance and agility. It supports a 65M~115M frequency band and integrates 4K memory. This allows it to be used in simple wireless control appliances such as toys.
