Si4707

Weather Band and SAME Data Receiver

Description

Features

The Si4707 is the industry's first weather band (WB) radio

receiver IC to include a specific area message encoding

(SAME) processor. Offering unmatched integration and

PCB space savings, the Si4707 requires only one external

component and less than 15 mm²of board area. Available

in a tiny 3 x 3 mm QFN package, it eliminates the need for

a front-end tuner IC, external ADC, DSP processor, RAM,

and numerous discrete components found in traditional

SAME weather band radios. The Si4707 weather band

receiver provides the space savings and low power

consumption necessary for portable devices while

delivering the high performance and design simplicity

desired for all weather alert radios.

- Weather band support (162.4–162.55 MHz)

- SAME processor

- Excellent SAME sensitivity

- Byte-wise data quality metrics

- Advanced error correction

- 1050 Hz alert tone detection

- Excellent real-world performance

- Freq synthesizer with integrated VCO

- Automatic frequency control (AFC)

- Automatic gain control (AGC)

- Adaptive noise suppression

- WB digital tuning

- Low-IF direct conversion with no external ceramic

filters

- Programmable reference clock

- Volume control

- Receive signal quality indicators (RSSI and SNR)

- 2-wire and 3-wire control interface

- Integrated LDO regulator

- 2.7 to 5.5 V supply voltage

- Firmware upgradeable

Leveraging Silicon Laboratories' proven and patented

Si4700/01 FM tuner's digital low intermediate frequency

(low-IF) receiver architecture, the Si4707 delivers superior

RF performance combined with sophisticated digital

processing to yield best-in-class audio quality and SAME

data sensitivity.

The high integration and complete system production test

simplifies design in, increases system quality, and

improves manufacturability.

The Si4707 is a feature-rich solution including 1050 Hz

tone detection, automatic frequency control, dynamic

channel bandwidth filters, and digital tuning. In addition, the

Si4707 provides a programmable reference clock and

supports an I²C compatible 2-wire control interface, SPI,

and a Si4700/01 backwards compatible 3-wire control

interface.

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

- Pb-free/RoHS compliant

Applications

- Emergency radios

- Table and portable radios

- Stereos

- Mini/micro systems

- Portable media players

- Boom boxes

The Si4707 incorporates a digital processor to provide

SAME data, advance error correction, and SAME data

quality metrics. Using this feature, the Si4707 enables

broadcast alert data such as severe thunderstorm warning

or flash flood watch to be displayed to the user.

- Cellular handsets

- Modules

- Clock radios

- Mini HiFi
