Si4710/11 FM Radio Transmitters

The Si4710/11 FM radio transmitter ICs are the industry's first 100% CMOS, single-chip FM transmitters. Built on the Silicon Labs FM receiver architecture, the Si4710/ offers unmatched integration and performance and allows FM transmitters 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 digital integration of the Si4710/11 ICs 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. The high reliability in device manufacturing, improved quality, simple design-in, and software programmability are key advantages of the Si4710/11 ICs.
