as well as the expensive external components needed for LNA
and AGC in the AM and FM front-ends. The TEF662x family
also integrates a VCO, so there’s no need for external LC tank
components.
The low-IF architecture simplifies PCB layout, since there
aren’t any critical high-frequency lines and there’s no need
for alignments. Even designers with limited RF know-how
or resources can design the TEF662x onto the main PCB
board, saving significant costs by making a tuner module
design obsolete. Manufacturing is also easier, since full SMD
applications, without hand mounting, are possible. Production
throughput can be higher, too, because there are fewer small
external components to handle, and there are no mechanical
or software alignments to be made.
