Recent generations of NXP’s one-chip low-IF tuners continue to expand the frontiers of front-end excellence. At the same time, increasing component integration reduces design complexity and cuts board space requirements.

Our TEF66xx ICs represents a real breakthrough innovation for the analog car radio market. They are the market’s frst alignment-free, low-IF tuners that can be designed directly onto the main board without in-depth RF know-how. This enables OEM and aftersales manufacturers to beneft from the technology while still reaching the high performance requirements for car radio applications.
With the increasing number of features in the car radio head unit, space also becomes an ever more critical issue. Helping you ft more into less, TEF66xx tuner ICs make traditional analog AM/FM tuner modules obsolete. In addition to having the tuner included on the main board, these ICs incorporate all critical RF components and therefore eliminating the need for those components. Fully pin compatible, the TEF66xx product family offers a range of different feature sets to suit your feature / pricing area.
