- In detail
The Si4736/37 ICs are the industry's first fully integrated, 100% CMOS AM/FM/WB and FM/WB radio receivers. Offering unmatched integration and PCB space savings, the Si4736/37 ICs require only two external components and less than 15 mm² of board area, excluding the antenna inputs.
The Si4736/37 AM/FM/WB radio ICs provide the space savings and low-power consumption necessary for portable devices while delivering the high performance and design simplicity desired for all AM/FM/WB solutions.
Leveraging Silicon Labs' proven and patented Si4700/01 FM tuner's digital low intermediate frequency (low-IF) receiver architecture, the Si4736/37 ICs deliver superior RF performance and interference rejection in both AM and FM bands. The high integration and complete system production test simplify design-in, increase system quality and improve manufacturability.
