The Si4313 offers a simple, single-ended radio implementation over the 240960 MHz frequency range. A receive sensitivity of up to 118 dBm allows for the creation of communication links with an extended range. Patents pending The Si4313 offers excellent receiver performance in cost-sensitive radio applications. The Si4313 provides designers with advanced features to enable low system power consumption by offloading a number of RF-related activities from the system MCU allowing for extended MCU sleep periods. Additional features, such as an automatic wake-up timer, 64-byte RX FIFO, and a preamble detection circuit, are available. The Si4313 s digital receive architecture features an ADC and DSP based modem that performs the radio demodulation and filtering for increased performance.
