PRELIMINARY
SYSTEMS APPLICATIONS
eIMR+ to TP Port Connection
The eIMR+ device provides a system solution
to designing non-managed multiport repeaters. The
eIMR+ device connects directly to AC coupling mod-
ules for a 10BASE-T hub. Figure 9 shows the simpli-
fied connection.
Twisted Pair Transmitters
TXD signals need to be properly terminated to meet the
electrical requirement for 10BASE-T transmitters.
Proper termination is shown in Figure 10 which consists
of a 110-
Ω resistor and a 1:1 transformer. The load is a
twisted-pair cable that meets IEEE 802.3, Section 14.4
specifications. The cable is terminated at the opposite
end by 100
Ω.
Twisted Pair Receivers
RXD signals need to be properly terminated to meet
the electrical requirements for 10BASE-T receivers.
Proper termination is shown in Figure 11. Note that the
receivers do not require external filter modules.
