Digi XBee SX 868 RF Module

Digi XBee SX 868 RF Module

RF module family operates in the 863-870 MHz range delivering superior performance and interference immunity at 868 MHz

• Low-power CE/RED certified 868 MHz RF module based on Silabs EFM32 and ADI7023
• Design includes SAW filter for optimal performance in noisy RF environments
• Listen-Before-Talk and Frequency Agility for optimal interference immunity
• DigiMesh® networking topology for redundancy and reliability

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 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 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 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.
