9.1.2 Using SPLIT With Split Termination

The SPLIT pin voltage output provides 0.5 × VCC in normal mode. The circuit may be used by the application to stabilized the common-mode voltage of the bus by connecting it to the center tap of split termination for the CAN network (see Figure 19 and Figure 20). This pin provides a stabilizing recessive voltage drive to offset leakage currents of unpowered transceivers or other bias imbalances that might bring the network common-mode voltage away from 0.5 × VCC. Using this feature in a CAN network improves electromagnetic emissions behavior of the network by eliminating fluctuations in the bus common-mode voltage levels at the start of message transmissions.
