Description

The Si4702/03 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

programmability, and superior, proven performance. Si4702/03

software is backwards compatible to existing Si4700/01 FM tuner

designs and leverages Silicon Laboratories' highly successful

and patented Si4700/01 FM tuner. The Si4702/03 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 10 mm

space and one external bypass capacitor.

The device offers significant programmability. It can be adapted

to subjective listening requirements, and it allows adjustability in

important parameters such as seek/tune, allowing the Si4702/03

to outperform other solutions by finding more valid stations and

not stopping on frequencies that do not have a radio station.

The Si4703 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 enables data such as station identification and song name

to be displayed to the user. The Si4703 offers a detailed RDS

view and a standard view, allowing adopters to selectively

choose granularity of RDS status, data, and block errors. Si4703

software is backwards compatible to the proven Si4701, adopted

by leading cell-phone and MP3 manufacturers world-wide.

The Si4702/03 is based on the superior, proven performance of

Silicon Laboratories' Aero architecture offering unmatched

interference rejection and leading sensitivity. The device uses

the same programming interface as the Si4700/01 and supports

multiple bus-modes. Power management is also simplified with

an integrated regulator allowing direct connection to a 2.7 to

5.5 V battery.

The Si4702/03 device’s high level of integration and complete

manufacturers, improves device yields, and simplifies device

manufacturing and final testing.
