product family.
The Si4313 offers a simple, single-ended radio implementation over the
240–960 MHz frequency range. A receive sensitivity of up to –118 dBm
allows for the creation of communication links with an extended range.
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.
