Silicon Laboratories’ Si4330 is a highly integrated, single chip wireless ISM
receiver. 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 Si4330 offers advanced radio features including continuous frequency
coverage from 240–960 MHz. The Si4330’s high level of integration offers
reduced BOM cost while simplifying the overall system design. The extremely low
receive sensitivity (–121 dBm) 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.
Additional system features such as an automatic wake-up timer, low battery
detector, 64 byte RX FIFO, automatic packet handling, and preamble detection
reduce overall current consumption and allow the use of a lower-cost system
MCU. An integrated temperature sensor, general purpose ADC, power-on-reset
(POR), and GPIOs further reduce overall system cost and size.
The Si4330’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.
An easy-to-use calculator is provided to quickly configure the radio settings,
simplifying customer's system design and reducing time to market.
