AM/FM tuner chips enable higher performance at less space

September 05, 2013 // By Christoph Hammerschmidt
NXP Semiconductors launched two new AM/FM single-chip car radio tuners for automotive entertainment. The TEF665x and TEF668x tuners combine RFCMOS technology with a broad feature set, best-in-class software algorithms and simplified integration.

Providing OEMs with increased flexibility, the tuners offer optional support of HD Radio and DRM digital radio standards via a co-processor such as NXP's SAF356x and SAF350x. With a significant reduction in footprint (-80%) and power dissipation (-50%) compared to its predecessor, the tuners provide premium performance at a low system cost, ideal for emerging and high-growth markets such as the BRIC countries.

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.

With the introduction of this next-generation tuner chips, NXP said it intends to further strengthen its portfolio on entry and mainstream tuner solutions focusing on car-OEM and aftermarket platforms in the BRIC countries.
