Datasheet
Document Number: 302875-005
Revision Date: 27-Oct-2005
As shown in
Figure 12,
in 100BASE-TX mode, the LXT972M Transceiver scrambles and
transmits the data to the network using MLT-3 line code. MLT-3 signals received from the network
are de-scrambled, decoded, and sent across the MII to the MAC.
