Description
The Si4700 is the industry's first FM radio tuner IC to
leverage digital integration and 100% CMOS process
technology, resulting in a completely integrated solution
that requires only one external supply bypass capacitor
and less than 20 mm
integration, the Si4700 allows FM radio reception to be
added to a variety of portable devices where board space,
performance, low power consumption, and ease of use are
essential.
Leveraging Silicon Laboratories' proven Aero
intermediate frequency (low-IF) receiver architecture and
frequency synthesizer technology, the Si4700 delivers
superior RF performance and interference rejection. Digital
signal processing is utilized to provide optimum sound
quality with varying reception conditions.
The high integration and complete system production test
simplifies design-in, increases quality, and improves
manufacturing. The Si4700 also uses a streamlined
programming model, which further reduces product
development time. Power management is also simplified
with an integrated regulator allowing direct connection to a
2.7 to 5.5 V battery.
The Si4701 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. Using this feature, the
Si4701 enables data such as station identification and
song name to be displayed to the user.
