NXP汽車(chē)及家庭劇院應用之FM/AM完整解決方案

NXP全球首創(chuàng )Low IF Tuner，TEF660x系列FM/AM調諧器廣泛應用于汽車(chē)收音機主機及家用音響等收音裝置。TEF660x系列調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(guān)鍵射頻元件，并省去了對手動(dòng)調節的需求。因此，設備制造商可以輕易的將調諧器應用在主機板上，不再需要調諧器模塊，從而在主機中節省了很大空間并降低了系統成本。目前已獲的日本JVC等一流廠(chǎng)商采用。

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