Silicon Labs SI4700 and SI4701 are entire FM tuners on a single chip, and they are tiny. I have their USB FM Radio and I use it every day on my PC, and I believe the same chip is in my Sony Ericsson phone. This is the one that uses the earphone wire as antenna, although it can be separate, as is demonstrated in the USB FM radio implementation and also their devkit. The 4701 adds European Radio Data System (RDS) and US Radio Broadcast Data System (RBDS) which can capture the station identification and song name. This FM tuner would be a good choice for Neo. Silicon Labs also has an even smaller version, AM/FM version, and also FM transmitter chips that would allow playback on car stereo for example.
I am planning to make some PCB boards with the SI4701 and minimal parts on them in the future, will be sold on ebay (I have surface mount reflow oven).
