Description
Silicon Laboratories’ Si4430/31/32 devices are highly integrated, single chip
wireless ISM transceivers. The high-performance 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 Si4430/31/32’s high level of integration offers reduced BOM cost while
simplifying the overall system design. The extremely low receive sensitivity
(–121 dBm) coupled with 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.
The Si4430/31/32 offers advanced radio features including continuous frequency
coverage from 240–960 MHz in 156 Hz or 312 Hz steps allowing precise tuning
control. 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 Si4430/31/32’s digital receive architecture features a high-performance ADC
and DSP based modem which performs demodulation, filtering, and packet
handling for increased flexibility and performance. The direct digital transmit
modulation and automatic PA power ramping ensure precise transmit modulation
and reduced spectral spreading ensuring compliance with global regulations
including FCC, ETSI, ARIB, and 802.15.4d regulations.
An easy-to-use calculator is provided to quickly configure the radio settings,
simplifying customer's system design and reducing time to market.
