NXP Releases New High-Performance Single-Chip AM/FM Radio Tuners

New Car-Radio Tuner chips, combine superior tuner performance and easy integration

NXP have just released the TEF665x and TEF668x, the next generation of its successful family of RFCMOS-based, high-performance AM/FM single-chip car radio tuners. The TEF665x and TEF668x tuners combine the latest RFCMOS technology with a broad feature set, best-in-class software algorithms and simplified integration, offering a high quality solution for car radios. Providing OEMs with increased flexibility, the tuners offer optional support of HD Radio and DRM digital radio standards via a NXP co-processor such as SAF356x and SAF350x. With a significant reduction in footprint (-80%) and power dissipation (-50%) compared to its predecessor, the tuners provide high performance at a low system cost, ideal for emerging and high-growth markets such as the BRIC countries.

NXP Release New High-Performance Single-Chip AM/FM Radio Tuners NXP maintains a strong focus on improving reception quality in challenging field conditions, including multipath reception caused by obstacles such as tall buildings or mountains. Special algorithms on the TEF668x such as improved multipath suppression (iMS) and channel equalizer (CEQ) ensure excellent sound quality during such conditions.

“At Desay SV, we are committed to providing best-in-class in-car infotainment solutions for car radios. The TEF668x tuners provide excellent performance levels with a broad feature set and unique flexibility. With a smaller footprint and simplified integration, NXP's latest tuner solutions are exactly what we need to address the requirements of high-growth BRIC markets,” said Mr. Yongzheng Duan, vice general manager at Desay SV. “We are pleased to continue building on our long-term relationship with NXP, leveraging its experience as the market leader in semiconductors for car entertainment.”

Torsten Lehmann, senior vice president and general manager car entertainment solutions at NXP Semiconductors, added: “The TEF665x and TEF668x family of tuners responds to our customers' demand for highly integrated, cost-effective, premium quality radio solutions. As a global leader in car entertainment semiconductors, NXP further strengthens its portfolio on entry and mainstream tuner solutions focusing on Car-OEM and aftermarket platforms in the BRIC countries.”
