Figure 20
shows the LXT972M Transceiver in a typical twisted-pair interface, with the RJ-45
connections configured for a NIC application.
Figure 20. Intel
LXT972M Transceiver Typical Twisted-Pair Interface - NIC
1. Center tap current may be supplied from 3.3 V VCCA as shown. Additional power savings may be
realized by supplying the center tap from a 2.5 V current source. A separate ferrite bead (rated at 50
mA) should be used to supply center-tap current.
2. The 100
Ω
transmit load termination resistor typically required is integrated in the LXT972M
Transceiver.
3. Magnetics without a receive pair center tap do not require a 2 kV termination.
4. RJ-45 connections shown for standard NIC. TX/RX crossover may be required for repeater and
switch applications.
