Si4702/03-C19

Broadcast FM Radio Tuner for Portable Applications

Description

Features

The Si4702/03-C19 extends Silicon Laboratories Si4700/

01 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. The Si4702/03 leverage Silicon

Laboratories' highly successful and patented Si4700/01 FM

tuner, and are pin and software compatible to existing

Si4700/01 FM tuner designs. The Si4702/03 benefits from

proven digital integration and 100% CMOS process

technology, resulting in a completely integrated solution.

The Si4702/03 proven and highly flexible functionality

caters to the subjective nature of audio preferences and

variable FM broadcast environments worldwide.

- Worldwide FM band support (76–108 MHz)

- 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

- Line-level analog output

- 32.768 kHz reference clock

- 2-wire and 3-wire control interface

- 2.7 to 5.5 V supply voltage

- Integrated LDO regulator allows direct connection

to battery

- 3 x 3 mm 20-pin QFN package

- Pb-free/RoHS compliant

- RDS/RBDS Processor (Si4703)

- Integrated crystal oscillator

The Si4703-C19 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, PND, and MP3

manufacturers worldwide.
