TDA7000 FM receiver chip vs Sparkfun FM Receiver Breakout Board (AR010)

I remember years ago when I saw in an electronics magazine I subscribed to (Radio Electronics, Poptronics?, etc.) a project I built that used the TDA7000 FM radio on a chip and the project would fit inside of a pack of gum or something small like that. I think at that time Radio Shack may have sold the chip also. I can't find reference to it on the internet now. But I found a company that sells all the parts (oops no pcb!) for a TDA7000 FM receiver and I bought it yesterday. http://electronics-diy.com/store.php?sel=kits&sub=fm_receivers

But then today I remember seeing on Sparkfun a month or two back an FM receiver module that is I2C or SPI programmable. I bought that today along with associated recommended parts (e.g. 3.3v p/s board, opamp breakout, audio jack breakout, etc). http://www.sparkfun.com/commerce/product_info.php?products_id=8972

I thought the one from Spark fun would be a good project to interface to an SX chip probably in SPI since it is a bit easier I think than I2C.

Has anyone got any experience with either of these FM receiver modules/chips?

Sounds like something cool to play around with and interface to a project perhaps.

    I used the TDA7000 many years ago on a home-made PCB, it worked quite quite well. The main disadvantage was the large number of components it needed. The Brighton amateur radio club designed it into a very simple packet radio receiver as a club project for members. Si Labs makes FM radio chips. I haven't tried them but they look very easy to use.

    Ditto Leon's recommendation of the Si Labs chips. I've not used one — yet — but, judging from their datasheets, they should be drop-dead simple to implement, and the number of external components required is virtually nil.

    These si labs chips look great. Ill have to look into these closer to see where I can get them at. I did not see them in DIP format but that just means a custom expensive pcb. Thanks for the news about these FM chips from si labs!

    I'm going to order the Si4704 this week. Leon said that Si Labs might offer samples but I did not see FM tuners listed on the samples list on their website. Mouser has the chip for $9.21. What is the name of that chip format?

    That article was presented a long time ago, 1988.

    If anyone wants to reminisce, here's the first page.· It probably wouldn't be right to post the entire article here.

    It's QFN - quad-flatpack no leads.

    I remember an article about the TDA7000... a long ago in an Electronics magazine published in Brazil and in Argentina (Saber (ed.) Electr

    No, mono only.
