Description
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.
The Si4432/31 offers advanced radio features, including
continuous
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
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.
