Wake-up behavior
Split Circuit
The split circuitry is activated during normal mode and deactivated (SPLIT pin floating) during
standby mode. The SPLIT pin is used to stabilize the recessive common mode signal in normal
mode. This is realized with a stabilized voltage of 0.5 VCC at SPLIT.
A correct application of the SPLIT pin is shown in Figure 7. The split termination for the left and
right node is realized with two 60 ⦠resistances and one 10 nF capacitor. The center node in this
example is a stub node and the recommended value for the split resistances is 1.5 kâ¦.
