5.0 Design Guidelines
5.1 TPI Network Circuit
Figure 11 shows the recommended circuit for a 10/100
Mb/s twisted pair interface. To the right is a partial list of
recommended transformers. It is important that the user
realize that variations with PCB and component character-
istics requires that the application be tested to ensure that
the circuit meets the requirements of the intended applica-
tion.
