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. 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. 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.

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.
