Split Circuit
The split circuitry is activated during normal and RxOnly mode and deactivated (SPLIT pin high
ohmic) during sleep and standby mode. The SPLIT pin is used to stabilize the recessive common
mode signal in normal mode and RxOnly mode. This is realized with a stabilized voltage of 0.5
V
Figure 5
A correct application of the SPLIT pin is shown in
right node is realized with two 60 Ω 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 kΩ.
