Minimizing the amount of space needed for the Ethernet LAN interface is important
because other interfaces compete for physical space on a motherboard near the
connector. The Ethernet LAN circuits need to be as close as possible to the connector.

differential pairs, but can be generalized for a Gigabit system with four analog pairs.
The ideal placement for the Ethernet silicon would be approximately one inch behind
the magnetics module.
While it is generally a good idea to minimize lengths and distances,
illustrates the need to keep the LAN silicon away from the edge of the board and the
magnetics module for best EMI performance.
Layout Guidelines for Use with Integrated and Discrete Magnetics
Layout requirements are slightly different when using discrete magnetics.
These include:

• Ground cut for HV installation (not required for integrated magnetics)
• A maximum of two (2) vias
• Turns less than 45
• Discrete terminators
