LOW-POWER RF
MODULE FOR EUROPE
DIGI XBEE® SX 868
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-tomultipoint networking protocol utilizing a low-power Silicon
Labs microcontroller and an Analog Devices ADF7023 transceiver,
along with an integrated SAW filter which offers 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 radio environment before any transmission starts, and
automatically shifting 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
software 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.
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
