DP83848 Layout question

Other Parts Discussed in Thread: DP83848I

Hello,

When it comes to the GND plane, can you confirm if there should be no ground plane under the Tx and Rx differential signals from the PHY to the magnetics, under the magnetics, or under the RJ45?  I have seen appnotes for other PHY manufactures that specify this contraint.

Thanks,

Belenie
