Repeaters
for CAN, CAN FD and
CAN-based higher layer protocols
Ixxat repeaters are used to establish a physical coupling of two or more segments of a CAN or CAN FD bus system. They can be used to implement tree or star topologies as well as for long drop lines. In addition, network segments can be electrically decoupled using a galvanically isolated repeater.


Increase reliability
CAN and CAN FD repeaters increase your system reliability with almost no influence on the real-time behavior.

For harsh environments
Ixxat repeaters decouple CAN or CAN FD segments galvanically up to 4 kV and are also available as variants with fiber optics.

Save costs
Easier wiring and reduction of cables reduces the cost of your system.
Learn more about the repeaters and see how they work
The lines coupled by the repeater are independent electric segments that can be optimally terminated in terms of signals. In this way topologies can be implemented that are not possible with a pure line of the bus due to electrical reflections. According to the transceiver output capacities, the division of a CAN / CAN FD system into several subsystems, connected via CAN / CAN FD repeaters, increases the maximum number of bus nodes. Using repeaters does not influence the real-time behavior of a system because in terms of transmission behavior it corresponds to a network that consists only of lines. In terms of signals, the repeater corresponds to a line with relevant delay time. Therefore, it cannot be used to extend a CAN / CAN FD system. However, using repeaters allows to increase the system dimensions indirectly, as shown in the sample.
