TomTom Adopts Silicon Laboratories' FM Radio Transmitter for Portable Navigation Devices.

Si4710 Offers Unmatched Performance in a Small Footprint

AUSTIN, Texas -- Silicon Laboratories Inc. (Nasdaq:SLAB) today announced that TomTom NV, the world's largest navigation solutions provider, has adopted the Si4710 FM transmitter for the new TomTom GO 520 and TomTom GO 720 portable navigation solutions. By using the highly-integrated Silicon Laboratories FM transmitter, the TomTom GO 520 and TomTom GO 720 are able to transmit music and navigation information over the car stereo.

The Si471x FM transmitter family is based on Silicon Laboratories' patented and proven digital architecture enabling industry-leading integration and high-quality sound fidelity for small footprint applications where performance is critical. TomTom's focus on the quality of the end-user experience along with an elegant, slim form factor design made the Si4710 FM transmitter an optimal solution for their navigation solutions. The innovative architecture of the Si4710 improves the stability of volume output on the receiving system and increases delivered audio fidelity of the transmitting system through unique digital signal processing algorithms implemented on the chip. The result is a higher fidelity audio experience for the end user and a simplified design for the customer.

"TomTom's products are developed with an emphasis on innovation, quality, ease-of-use and value in order to deliver the best navigation experience on the market," said Eric Pite, vice president of product management for TomTom. "Silicon Laboratories' innovative FM transmitter offers the performance and end-user experience our customers have come to expect."

Available in a very small 3 x 3 x 0.55 20-pin QFN package, the Si471x transmitter family significantly reduces the bill of materials and power consumption when compared to alternative solutions. In addition to the Si4710, Silicon Laboratories' FM transmitter family includes pin-compatible FM RDS transmitters (Si4711/13) and FM receive power scan (RPS) transmitters (Si4712/13) requiring only two external components and implemented in 15 mm2 of printed circuit board area. The Si471x FM transmitter family also offers customers a fully tested solution that speeds time-to-market and simplifies manufacturing.

"We developed the FM transmitter with a no-compromise philosophy that results in market-leading integration combined with best-in-class performance," said Tyson Tuttle, vice president of Silicon Laboratories. "We have made FM transmit a simple, cost effective feature to add to portable devices."
