Si4712/13

FM Radio Transmitter with Receive Power Scan

Description

Features

The Si4712/13 is the industry's first 100% CMOS FM

radio transmitter with an integrated receiver to

measure receive signal strength. 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 Si4712/13 offers

industry leading size, performance, low power

consumption, and ease of use.

- Integrated receiver for receive power measurement

- 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 (Si4713 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 Si4712/13’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

Si4712/13.

- Integrated LDO regulator

- 3 x 3 x 0.55 mm 20-pin QFN

- Pb-free and RoHS Compliant

The Si4713 supports the European Radio Data

System (RDS) and the US Radio Broadcast Data

System (RBDS) standards including all the symbol

encoding, block synchronization, and error correction

functions. Using this feature, the Si4713 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 for adjusting their system’s

radiated power levels to comply with local regulations

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