NXP全球首創(chuàng)Low IF Tuner，TEF660x系列FM/AM調(diào)諧器廣泛應用于汽車收音機主機及家用音響等收音裝置。TEF660x系列調(diào)諧器采用了突破性的整合設計，在單一芯片上整合了全部關鍵射頻元件，并省去了對手動調(diào)節(jié)的需求。因此，設備制造商可以輕易的將調(diào)諧器應用在主機板上，不再需要調(diào)諧器模塊，從而在主機中節(jié)省了很大空間并降低了系統(tǒng)成本。目前已獲的日本JVC等一流廠商采用。

TEF6601和TEF6606整合了全部的關鍵射頻元件，包括：壓控振蕩器，陶瓷濾波器，IF變壓線圈，低噪音放大器和自動增益控制，只需要32個低成本的外圍元件。此外，通過特殊的大信號處理的功能，這款低IF調(diào)諧器支持汽車收音機應用的高性能需求。
