Description
The RDA5156 is a single-chip FM transceiver that can be used in portable devices such as MP3 and MP4 players, PDAs, cellular handsets, portable radios, and wireless toys. It uses the CMOS process and requires the least external component. It has a powerful low-IF digital audio processor that provides optimum sound quality with varying reception conditions. The RDA5156 uses RDA patented dual synthesizers, an all-digital transmit structure, and supports multi-interface. Its package size is 4X4mm, which makes it completely adjustment-free. All these features make this model ideal for simple wireless control appliances such as toys and other portable devices.
