Hello team,
A customer is using DP83822 in their design and has a question regarding a note for PCB layout. On page 101 of the datasheet (http://www.ti.com/lit/ds/symlink/dp83822i.pdf), it says:
On page 94, it also says: "5. Avoid supplies and ground beneath the magnetics
In a normal PCB design, my customer typically adds a solid ground plan to shield the sensitive signal traces from the noise source. Is there particular reason that they cannot do this for a magnetics?
Why is it recommended to remove all the metal layers under the transformer?
