APPLICATION EXAMPLEBENEFITS
– Low-power CE/RED certified 868MHz RF module based
on Silabs EFM32 and ADI7023
– Design includes SAW filter for optimal performance in
noisy RF environments
– OTA and pin compatible with legacy Digi XBee 868LP
– Listen-Before-Talk and Frequency Agility for optimal
interference immunity
– DigiMesh networking topology for redundancy and
reliability
– Simple configuration using X-CTU accelerates time
to market
RF module family operates in the 863-870 MHz range delivering
superior performance and interference immunity at 868 MHz
The Digi XBee SX 868 is an 868 MHz RF module for Europe. The
module can run either a proprietary DigiMesh® or point-to-
multipoint networking protocol utilizing a low-power Silicon
Labs microcontroller and an Analog Devices ADF7023 transceiver,
along with an integrated SAW filter which oers industry-leading
interference blocking. The Digi XBee SX 868 operates between 863
MHz and 870 MHz, making it deployable in several regions throughout
the world including approved European countries.
The Digi XBee SX 868 also leverages 868 MHz and surrounding
frequencies for LBT + AFA (Listen Before Talk and Adaptive Frequency
Agility). This significantly reduces interference by listening to
DIGI XBEE® SX 868
the radio environment before any transmission starts, and
automatically shiing to a new channel when interference is
detected. This patented frequency scan occurs automatically and in
a matter of microseconds so as not to impact performance.
The DigiXBee SX 868 RF module is a complete hardware and
soware solution that works directly out of the box. X-CTU, Digi’s
easy-to-use RF configuration tool, reduces development time from
months to weeks, ensuring your product gets to market fast.

*Range figure estimates are based on free-air terrain with limited sources of interference. Actual range will vary based on transmitting power, orientation of transmitter and receiver,
height of transmitting antenna, height of receiving antenna, weather conditions, interference sources in the area, and terrain between receiver and transmitter, including indoor and
outdoor structures such as walls, trees, buildings, hills, and mountains.
