DP83867IR: How to choise the magnetics

Takahiro Ogo

Part Number: DP83867IR
Other Parts Discussed in Thread: DP83848K

Hi,

My customer will use DP83867IR. And then, for thier board, they are considering the Magnetic device as below. Can they use all these magnetics for DP83867IR board?
・HX6062FNL　PULSE
・HM6098FNL　PULSE
・HX6098NL　PULSE
・HX6096NL　PULSE

By the way, why are there any "Magnetics Requirement" and specificaton in DP83867IR datasheet? Also, There is no the design guide for DP83867.
I know there are "Magnetics Requirement" in datasheet for other ether phy. (ex. DP83848K)

Best Regards,
Taka
