Can anyone explain this IC for me?

Hi all,



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

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!

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.

Right, see figure 9 in the datasheet. They show an added RF amplifier, oscillator / mixer and a 10.7MHz IF crystal filter.
