Si4730/31

Broadcast AM/FM Radio Receiver

Description

Features

The Si4730/31 is the industry's first fully integrated, 100%

CMOS AM/FM radio receiver IC. The Si4730/31 AM/FM

radio provides the space savings and low power

consumption necessary for portable devices while

delivering the high performance and design simplicity

desired for all AM/FM solutions. Offering unmatched

integration and PCB space savings, the Si4730/31

requires only two external components and less than 15

mm²of board area.

- Worldwide FM band support (76–108 MHz)

- Worldwide AM band support (520–1710 kHz)

- AM/FM digital tuning

- Excellent real-world performance

- Only 2 external components

- No manual alignment required

- Adjustable AM channel filters

- Advanced AM/FM seek tuning

- Digital volume control

Leveraging Silicon Laboratories' proven and patented

Si4700/01 FM digital receiver architecture, the Si4730/31

delivers superior RF performance and interference

rejection in both AM and FM bands. The high integration

and complete system production test simplifies design-in,

increases system quality, and improves manufacturability.

The Si4730/31 solution includes advanced seek

algorithms, adjustable soft mute, auto-calibrated digital

tuning, and FM stereo processing. In addition, the Si4730/

31 provides a programmable reference clock, I²C-

compatible 2-wire control interface, and a Si4700/01

backwards-compatible 3-wire control interface.

- Adjustable soft mute control

- Frequency synthesizer with integrated VCO

- Automatic frequency control (AFC)

- Automatic gain control (AGC)

- Programmable AM/FM de-emphasis

- Adaptive noise suppression

- Integrated LDO regulator

- Programmable reference clock

- FM RDS/RBDS processor (Si4731 only)

- 2-wire and 3-wire control interface

- 2.7 to 5.5 V supply voltage

The Si4730/31 utilizes digital processing to achieve high

fidelity, optimal performance, and design flexibility. The

chip provides excellent pilot rejection, selectivity, and

unmatched audio performance, and offers both the

manufacturer and the end-user extensive programmability

and flexibility in listening experience.

- AM ferrite loopstick and air loop antenna support

- 3 x 3 x 0.55 mm 20-pin QFN package

- Pb-free/RoHS compliant

Applications

- Table and portable radios

The Si4731 incorporates a digital processor for the

European Radio Data System (RDS) and the North

American Radio Broadcast Data System (RBDS)

including all required symbol decoding, block

synchronization, error detection, and error correction

functions. Using this feature, the Si4731 enables

broadcast data such as station identification and song

name to be displayed to the end user.

- Stereos

- Mini/micro systems

- Portable media players

- Boomboxes

- Cellular handsets

- Clock radios

- Modules

- Entertainment systems
