Si4710/11

FM Radio Transmitter for Portable Applications

Description

Features

The Si4710/11 is the industry's first 100% CMOS FM

transmitter single chip IC. The device leverages

Silicon Labs’ highly successful and proven Si4700/01

FM receiver, and offers unmatched integration and

performance allowing FM transmit to be added to any

portable device by using a single chip. As with the

Si4700/01, the Si4710/11 offers industry leading size,

performance, low power consumption, and ease of

use.

- Worldwide FM band support

(76–108 MHz) for transmit

- Requires only two external components

- Frequency synthesizer with integrated VCO

- Digital stereo modulator

- Programmable pre-emphasis

(50/75 µs)

- Analog/digital audio interface

- Programmable reference clock

- RDS/RBDS transmit encoder (Si4711 only)

- PCB loop antenna support with self calibrated

capacitor tuning

- Programmable transmit level

- Programmable modulation

- 2.7 to 5.5 V supply voltage

- Digital gain compression

The Si4710/11’s digital integration reduces the

required external components of traditional offerings,

resulting in a solution requiring only an external

inductor and bypass capacitor, and PCB space of

approximately 15 mm . High reliability in device

manufacturing, improved quality, easy design-in, and

software programmability are key advantages of the

Si4710/11.

- Integrated LDO regulator

- 3 x 3 x 0.55 mm 20-pin QFN

- Pb-free and RoHS Compliant

The Si4711 supports the European Radio Data

System (RDS) and the US Radio Broadcast Data

System (RBDS) including all the symbol encoding,

block synchronization, and error correction functions.

Using this feature, the Si4711 enables data such as

artist name and song title to be transmitted to an

RDS/RBDS receiver.

Applications

- Cellular handsets/hands-free

- MP3 players

- Portable audio/video players

- Wireless speakers/microphone

- Satellite digital audio radios

- Personal computers/notebooks

Users are responsible to adjust their system’s

radiated power levels to comply with local regulations

on RF transmission (FCC, ETSI, ARIB, etc.).
