Si4734/35

Broadcast AM/FM/SW/LW Radio Receiver

Description

Features

The Si4734/35 is the industry's first fully integrated, 100%

CMOS AM/FM/SW/LW radio receiver IC. Offering

unmatched integration and PCB space savings, the

Si4734/35 requires minimal external components and less

than 20 mm²of board area, excluding the antenna inputs.

The Si4734/35 AM/FM/SW/LW 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/SW/LW solutions.

- Worldwide FM band support (64–108 MHz)

- Worldwide AM band support(520–1710 kHz)

- SW band support (2.3–21.85 MHz)

- LW band support (153–279 KHz)

- Excellent real-world performance

- Freq synthesizer with integrated VCO

- Automatic frequency control (AFC)

- Automatic gain control (AGC)

- Integrated LDO regulator

- Digital FM stereo decoder

- Programmable de-emphasis

- Adaptive noise suppression

- AM/FM/SW/LW digital tuning

- No manual alignment necessary

- Adjustable channel filters

- EN55020 complaint

- Programmable reference clock

- Digital volume control

Leveraging Silicon Laboratories' proven and patented

Si4700/01 FM tuner's digital low intermediate frequency

(low-IF) receiver architecture, the Si4734/35 delivers

superior RF performance and interference rejection in AM,

FM, and short wave and long wave bands. The high

integration and complete system production test simplifies

design-in, increases system quality, and improves

manufacturability.

The Si4734/35 is

feature-rich solution including

- Adjustable soft mute control

advanced seek algorithms, soft mute, auto-calibrated

digital tuning, and FM stereo processing. In addition, the

Si4734/35 provides analog or digital audio output and a

programmable reference clock. The device supports I²C-

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

backwards-compatible 3-wire control interface.

- RDS/RBDS processor (Si4735 only)

- Optional digital audio out (Si4735 only)

- 2-wire and 3-wire control interface

- 2.7 to 5.5 V supply voltage

- Wide range of ferrite loop sticks and air loop antennas

supported

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

- Pb-free/RoHS compliant

The Si4734/35 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 the listening experience.

Applications

- Table and portable radios

- Stereos

The Si4735 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 RDS, the

Si4735 enables broadcast data such as station

identification and song name to be displayed to the user.

- Mini/micro systems

- Portable media players

- Boomboxes

- Clock radios

- Modules

- Entertainment systems

- Cellular handsets
