The Silicon Labs Si4330 is a low power, highly sensitive, OOK/FSK and GFSK receiver. As a member of the EZRadioPRO® family, it is designed for applications requiring FCC or ETSI conformance for unlicensed use between 240 and 960 MHz. The Si4330 is an industry-leading receiver IC, offering a sensitivity of -117 dBm and a diversity of embedded antenna algorithms. When used with Silicon Labs' other transmitter and transceiver products, designs with ranges of more than 2000 m. The Si4330 provides a variety of built-in features aimed at reducing the overall system BOM such as a wake-up timer, a low-battery detector, a 64 byte receive FIFO, a power-on reset circuit and general-purpose digital I/Os. The wireless IC incorporates a high-performance ADC and digital modem, which perform demodulation, filtering and packet handling in the digital domain, making the IC ideal for configuration to multiple applications. These features simplify system design tasks and allow the use of cost-effective microcontrollers. A 30 MHz crystal and supply bypass capacitors are the only necessary external components, making the Si4330 ideal for high-volume production in applications where small size and low cost are important.
