4 Application Information
4.1 Example Schematics
A typical example of the L84225 used for a switching hub application in
twisted pair mode is shown in
Figure 11
; an example of the L84225 used
in fiber mode is shown in
Figure 12
.
4.2 TP Interface
4.2.1 Transmit Interface
The interface between the TP outputs on TPOP/N and the twisted pair
cable is typically transformer coupled and terminated with the two
resistors as shown in
Figure 11
.
The transformer for the transmitter is recommended to have a winding
ratio of 1:1 with the center tap of the primary winding tied to VDD, as
shown in
Figure 11
. The specifications for such a transformer are shown
in
Table 21
. Sources for quad transformers compatible with the L84225
are listed in
Table 22
. Note that both “Stacked” and “Non-Stacked” pinout
types are listed. The Stacked and Non-Stacked designation refers to the
