The high-performance EZRadioPRO family includes a complete line of transmitters, receivers, and transceivers allowing the RF system designer to Patents pending choose the optimal wireless part for their application. The Si4330 offers advanced radio features including continuous frequency coverage from 240960MHz. The Si4330s high level of integration offers reduced BOM cost while simplifying the overall system design. The extremely low receive sensitivity (121dBm) 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 Si4330s 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.
