Can anyone explain this IC for me?

Hi all,

I am looking at the TDA1083 IC. The datasheet shows the following

I'm trying to figure out where the input for the FM signal goes. This
IC is supposed to be an AM/FM receiver, but this newbie is a bit
clueless as to where the FM antenna and matching network should be
connected.

Any tips?

Thanks!

Grab a copy of the complete data sheet:
http://pdf.alldatasheet.com/datasheet-pdf/view/26086/TEMIC/TDA1083.html
it comes with a sample circuit for an AM/FM radio.

Cheers.

Please go to wikipedia and look up the difference between "cross
posting" and "multiple posting". Only one is considered to be good
style, and then only under some circumstances.

* The IC has no RF stages for FM signals.

It is NOT a complete FM receiver.
