To minimize common mode output noise and to aid in meeting radiated
emissions requirements, it may be necessary to add a common mode
choke on the transmit outputs as well as add common mode bundle
termination. The transformers listed in
Table 22
all contain common
mode chokes on both the transmit and receive sides, as shown in
Figure 11
. Common mode bundle termination is achieved by tying the
unused pairs in the RJ45 to chassis ground through 75 ohm resistors
and a 0.01 uF capacitor, as shown in
Figure 11
.
To minimize noise pickup into the transmit path in a system or on a PCB,
the loading on TPOP/N should be minimized and both outputs should
always be loaded equally.
