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
transmit load termination resistor typically required is integrated in the
LXT971A.
3. Magnetics without a receive pair center-tap do not require a 2 kV termination.
4. RJ-45 connections shown are for a standard switch application. For a standard NIC RJ-45
setup, see
Figure 23 on page 50
