Application Notes
The Fast Ethernet to Gigabit Ethernet interchangeable
design is a design concept that allows design engineers
to design a network applications board that can support
both Fast Ethernet (10/100Base-T) and Gigabit Ethernet
(1000Base-T) applications by simply replacing several
components without having to re-design the whole board.
Two components that play a part in this design are the
Ethernet silicon and the transformer. Both the silicon and
the transformer for both 10/100 and gigabit must have
footprint compatibility. This footprint compatibility will
mean a single board layout for the interface between the
Ethernet silicon and the transformer of either 10/100 or
gigabit applications.
Presently, if a network design engineer wants to design a
10/100 card, he would have to choose a 10/100
transformer. If the engineer wants to design a gigabit
card, he would have to choose a gigabit transformer. This
leads to two different designs (board layout) for two
different applications.
The objective of interchangeable design is to allow the
engineer to utilize the same design (and board layout) for
10/100 and for a gigabit design (and vice versa) with
minimal change as possible to the design.

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.
