Its probably LXT PHYs from Level One that Intel has
used in its previous chips and not Marvell.
I think the jacks come in different versions with
1:1.25 or 1:1 ratios as required for different PHYs.
We used the integrated jack in a prototype but didnt
go for any EMC compliance tests so I have no further
info on this.
regards,
Jai
