Achieving a high EMC performance is not only a matter of the transceiver, a careful system implemen-
tation (termination, topology, external circuitry) is also very important. This chapter presents some
application hints aiming to exploit the outstanding EMC performance of the TJA1050.

Practice has shown that effective reduction of emission can be achieved by a modified bus termination
concept called split termination. In addition this concept contributes to higher immunity of the bus
system.
The split termination concept is illustrated in Figure 4.1. Basically each of the two termination resistors of
the bus line end nodes is split into two resistors of equal value, i.e. two resistors of 60
instead of one
resistor of 120
. As an option, stub nodes, which are connected to the bus via stubs, can be equipped with
a similar split termination configuration. The resistor value for the stub nodes has to be chosen such that
the bus load of all the termination resistors stays within the specified range from 50
to 65
number of 10 nodes (8 stub nodes and 2 bus end nodes) a typical resistor value is 1,3k
.

Figure 4.1 Typical split termination concept
The special characteristic of this approach is that the common mode signal is available at the centre tap of
the termination. This common mode signal is terminated to ground via a capacitor C
