The above circuit is a simple interface for a gigabit transformer connectiong to both the Gigabit Ethernet silicon and the RJ-45 connector.
It is highly recommended that the cable side Center Taps of each transformer be terminated to 75 Ω resistors and that the four center taps be
terminated to an EFI capacitor prior to ground termination.
