Si4432/31/30

ISM Transceiver

Description

Features

Silicon Laboratories’ Si4432/31/30 highly-integrated, single chip

wireless ISM transceiver is part of the EZRadioPRO™ family. The

EZRadioPRO family includes a complete line of transmitters,

receivers, and transceivers allowing the RF system designer to

choose the optimal wireless part for their application.

Frequency Range = 240–930 MHz (Si4432/31)

900–960 MHz (Si4430)

Sensitivity = –118 dBm

FSK, GFSK, and OOK modulation

Max Output Power = +20 dBm (Si4432)

+13 dBm (Si4431/30)

The Si4432/31 offers advanced radio features, including

continuous frequency coverage from 240–930 MHz and

adjustable output power of up to +20 dBm with the Si4432. The

Si4430 offers frequency coverage from 900 to 960 MHz to support

the Japanese frequency bands. The Si4432/31/30’s high level of

integration offers reduced BOM cost while simplifying overall

system design. The extremely low receive sensitivity (–118 dBm)

coupled with the Si4432’s industry-leading +20 dBm output power

ensures extended range and improved link performance. Built-in

antenna diversity and support for frequency hopping can be used

to further extend range and enhance performance. Antenna

diversity is completely integrated into the Si443x and can improve

the system link budget by 8–10 dB, resulting in substantial range

increases under adverse environmental conditions.

Additional system features, such as an automatic wake-up timer,

low battery detector, 64 byte TX/RX FIFOs, automatic packet

handling, and preamble detection, reduce overall current

consumption and allow the use of lower-cost system MCUs. An

integrated temperature sensor, general-purpose ADC, power-on-

reset (POR), and GPIOs further reduce overall system cost and

size.

The Si4432/31/30 receiver uses a single-conversion architecture

to convert the 2-level FSK/GFSK/OOK modulated receive signal to

a low IF frequency. Following a programmable gain amplifier

(PGA) the signal is converted to the digital domain by a high-

performance delta-sigma ADC allowing filtering, demodulation,

slicing, error correction, and packet handling to be performed in

the built-in DSP, increasing the receiver’s performance and

flexibility versus analog based architectures.

The PA is single-ended to allow for easy antenna matching and

low BOM cost. The digital transmit modulation and automatic PA

power ramping ensure precise transmit modulation and reduced

spectral splatter, ensuring compliance with FCC and ETSI

regulations. The Si4430 is designed to ensure compliance with

ARIB regulations. The Si4432/31/30 is designed to work with an

MCU, crystal, and a few passives to create a very low-cost

system. Voltage regulators are integrated on-chip, which allows for

a wide range of operating supply voltage conditions from +1.8 to

+3.6 V.
