Re: fm receiver

ok there's 2 approaches you could use....

separate IF IC and Decoder IC eg....

TEA5570 AM-FM RX IF followed by a TEA5580 Stereo PLL Decoder

or an all in one IC ....

TEA5711 complete AM-FM Stereo RX IC

look up any of those TEAxxxx chips in google and you will find the datasheets that have complete example circuits for you to follow

The TDA7088T is one of the simplest around. It is not very sophisticated but works surprisingly well and is used in a lot of low cost radios. There is a Chinese imitation as well (called the CD9088 I think).
