Datasheet
Figure 22. Typical Twisted-Pair Interface - NIC
1. Center tap current may be supplied from 3.3V VCCA as shown. Additional power savings may be realized by supplying the
center tap from a 2.5V current source. A separate ferrite bead (rated at 50 mA) should be used to supply center tap current.
2. The 100
transmit load termination resistor typically required is integrated in the LXT972A.
3. Magnetics without a receive pair center tap do not require a 2kV termination.
4. RJ-45 connections shown are for a standard NIC. Tx/Rx crossover may be required for repeater & switch applications.
