Si4702/03

Broadcast FM Radio Tuner for Portable Applications

Description

Features

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 board area, minimum component count, flexible

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

- Worldwide FM band support (76–108 MHz)

- 3x3 mm 20-pin QFN package

- Pb-free/RoHS compliant

- Digital low-IF receiver

- Frequency synthesizer with integrated VCO

- Seek tuning

- Automatic frequency control (AFC)

- Automatic gain control (AGC)

- Excellent overload immunity

- Signal strength measurement

- Programmable de-emphasis (50/75 µs)

- Adaptive noise suppression

- Volume control

smallest footprint FM tuner IC requiring only 10 mm board

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.

- Line-level analog output

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.

- 32.768 kHz reference clock

- RDS/RBDS processor (Si4703 only)

- 2-wire and 3-wire control interface

- 2.7 to 5.5 V supply voltage

- Integrated LDO regulator allows direct connection

to battery

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.

Applications

- Cellular handsets

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.

- MP3 players

- PDAs, Notebook PCs

- Portable radios

- Portable navigation

- Automobile applications

- Consumer electronics

- USB FM radios

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

FM system production testing increases quality to

manufacturers, improves device yields, and simplifies device

manufacturing and final testing.
