with an external biasing circuit in order to achieve an optimum EMC performance. Figure 7.4 illustrates
the external biasing circuit, formed by the resistors R1 and R2, together with the split termination. The
resistor values of R1 and R2 (respectively R
T/2
) should match in pairs as close as possible. A reasonable
value range for R1 and R2 is from 1k
to 2k
. The presented external biasing concept is only applicable
to clamp-30 nodes because they are always powered.

Another important issue with respect to an unpowered transceiver is illustrated in Figure 7.5. There are
applications known where the transceiver is unpowered in order to achieve low power consumption, while
the microcontroller/CAN-controller remains powered and is put into its standby mode.
