8.2.2.1 CAN Termination

Termination may be a single 120Ω resistor at the end of the bus on either the cable or in a terminating node. If filtering and stabilization of the common mode voltage of the bus is desired, then split termination may be used, see Figure 8-2. Split termination improves the electromagnetic emissions behavior of the network by filtering higher-frequency common-mode noise that may be present on the differential signal lines.
