10/100 ETHERNET PROTECTION CONT’
Ethernet circuit to provide differential and common
mode protection. The SRV05-4 can not be grounded
on the line side because the hi-pot test requires the
line side not to be grounded.
GIGABIT ETHERNET PROTECTION
The clock rate of gigabit Ethernet is the same 125MHz
as the 10/100 Ethernet. However, it uses a complex
five level signaling and transmits at a faster data rate
that makes it more susceptible to capacitance and
insertion loss. The low capacitance and low insertion
loss of the SRV05-4 allow it to sit on the gigabit
Ethernet line without loss of signal integrity. Figure 10
shows how to connect the SRV05-4 into a gigabit
ethernet on the IC side for common and differential
mode protection. Notice that pin 5 of the SRV05-4 is
not connected. Some may be tempted to connect it to
Vcc. In the ethernet application, the Vcc lines does

not come out through the connector and does not
need to be protected. Figure 10 shows the LC03-3.3
on the line side for the secondary line protection to
Bellcore 1089 intrabuilding. If the designer only needs
to meet ESD, CDE and low level lightning, the LC03-
3.3 can be omitted.
