Silicon Labs Passes 1 Billion Radio Chip Mark

Now has 40+ broadcast audio products

Silicon Laboratories says it has now shipped 1 billion broadcast radio ICs.

The Austin, Texas-based company introduced its first single-chip FM receiver in 2005, the Si4700 IC, a small, multipurpose, integrated FM broadcast radio chip.

At that time, traditional broadcast audio solutions were based on complex, analog architectures that required more than 30 discrete components, according to SiLabs, which says the Si4700 design offered improved performance, reduced parts count and a smaller footprint on circuit boards.

Silicon Labs’ digital CMOS broadcast radio chips are used in handsets, portable media players, personal navigation devices, automotive infotainment systems, tabletop and bedside radios, portable radios, boom boxes and other consumer electronics products.

Silicon Labs’ Broadcast Audio Products GM Diwakar Vishakhadatta said: “Our single-chip FM, AM/FM receiver and transceiver families… have helped our customers reduce the cost and complexity of their designs while enabling more features and functionality to help them differentiate their products in the marketplace.”
