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.

Easy to design on the main PCB

• Small application PCB area

• No critical external RF components due

to highest integration

– only 34 (all passive SMD) components required

– complete channel selectivity / VCO integrated

• Limited resources and RF know-how needed

• Supports single layer PCB design

Easy to manufacture

• Full SMD application possible (no hand mounting)

• Less handling due to small number of external

components

• No mechanical / software alignments needed

• Higher production throughput
