10/100BASE-T SINGLE PORT,
SMT TRANSFORMER
For Fast Ethernet to Gigabit Ethernet
Interchangeable Designs
Application Circuit
H1267
W
The above circuit is a simple interface for a Fast Ethernet tranformer connecting to both the Fast Ethernet silicon and the RJ-45 connector. In order
to design a gigabit application, simply replace the Fast Ethernet Silicon, the Fast Ethernet transformer and the rest of the passive components with a
gigabit ethernet silicon, a gigabit transformer and the rest of the passive components.
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.
