The Si4710/11 FM radio transmitter ICs are the industry's first 100% CMOS, single-chip FM transmitters. The devices leverage Silicon Labs’ proven Si4700/01 FM receiver architecture and offer unmatched integration and performance, allowing FM transmit to be added to any portable device with a single chip. As with the Si4700/01 ICs, the Si4710/11 FM transmitters offer industry-leading size, performance, low-power consumption and ease of use.
The Si4710/11 ICs digital integration reduces the required external components of traditional offerings, resulting in a solution requiring only an external inductor and bypass capacitor and PCB space of approximately 15 mm2. High reliability in device manufacturing, improved quality, easy design-in and software programmability are key advantages of the Si4710/11 ICs.
The Si4711 supports the European Radio Data System (RDS) and the US Radio Broadcast Data System (RBDS) standards including all the symbol encoding, block synchronization and error correction functions. Using this feature, the Si4711 enables data such as artist name and song title to be transmitted to an RDS/RBDS receiver.
Users are responsible for adjusting their system’s radiated power levels to comply with local regulations on RF transmission (FCC, ETSI, ARIB, etc).
