3.7 FM Radio (Si4708)
Figure.3-7 Si4708 FUNCTIONAL BLOCK DIAGRAM
The Si4708/09 extends Silicon Laboratories Si4700 FM tuner family, and further increases the
ease and attractiveness of adding FM radio reception to mobile devices through small size and
board area, minimum component count, flexible programmability, and superior, proven
performance. Si4708/09 software is backwards compatible to existing Si4700/01/02/03 FM
Tuner designs and leverages Silicon Laboratories' highly successful and patented Si4700/01/02/03
FM tuner. The Si4708/09 benefits from proven digital integration and 100% CMOS process
technology, resulting in a completely integrated solution. It is the industry's smallest footprint FM
tuner IC requiring only 6.25 mm2 board space and one external bypass
capacitor.
The device offers significant programmability, catering to the subjective nature of FM listeners’
audio preferences and variable FM broadcast environments worldwide.
The Si4709 incorporates a digital processor for the European Radio Data System (RDS) and the
US Radio Broadcast Data System (RBDS) including all required symbol decoding, block
synchronization, error detection, and error correction functions.
RDS/RDBS* enables data such as station identification and song name to be displayed to the
user. The Si4709 offers a detailed RDS view and a standard view, allowing adopters to selectively
choose granularity of software is backwards compatible to the proven Si4701/03, adopted by
leading cell-phone and MP3 manufacturers world-wide.
The Si4708/09 is based on the superior, proven performance of Silicon Laboratories' Aero
architecture offering unmatched interference rejection and leading sensitivity. The device uses the
