Si4710/11 FM Radio Transmitters

 

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.
