Typical AM/FM Receiver Using Atmel´s Front-end Solution (Simplified)

The so called DIF (digital IF) architecture is currently a basic architectural approach for car media applications. As AM/FM will be in existance for long time in parallel to upcoming digital modulations (such as DAB, HD Radio or DRM), the DIF approach is a good way towards multi-standard solutions. Atmel's new front-end ICs are multi- standard solutions since they can be

used for both DIF-based solutions (sup- porting different baseband solutions), as well as for any other standard.

As for all other radio solutions, Atmel provides intensive design-in support, ranging from real design engineers to demo boards and evaluation kits as well as detailed documentation, to speed-up the time to market.
