NXP low-IF analog car radio tuner family TEF66xx
A family for all your analog
radio reception needs
Our TEF66xx ICs represents a real breakthrough
innovation for the analog car radio market.
They are the market’s first 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 benefit
from the technology while still reaching the high
performance requirements for car radio applications.
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.
Alignment free easy application
analog car radio tuners
With the increasing number of features in the
car radio head unit, space also becomes an ever
more critical issue. Helping you fit 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.
NXP’s TEF66xx family has been developed with our
strategic partner, Catena Radio Design, together
with a number of key customers. This ensures the
family offers a choice of features and performance
to meet a variety of price points.

The benefits of NXP’s
proven low-IF architecture
Whereas existing solutions require double IF
conversion, our TEF66xx devices eliminate both
10.7 MHz and 450 kHz IF transformer coils and
ceramics, as well as the expensive external
components for LNA and AGC in the AM and FM
front-ends. Additionally the fully integrated VCO
saves the external LC tank components.
Due to the low IF architecture, there are no critical
high frequency PCB layouts and alignments needed
anymore. Therefore, even set makers with limited RF
know-how or resources can apply the TEF66xx to the
main PCB board, saving significant costs by making
a tuner module design obsolete. Manufacturing is
also made easier by enabling full SMD applications.
Single layer PCB design is supported as well.
