Part Number: DP83867IR

I found the magnetic isolation characteristic in the datasheet. Page.117

The open circuit inductance is from 320uH to 350uH.

so, What happens if I use an inductance of less than 320uH?

Thank you.

Hello,

You may see some impact in the MDI signal as the magnetic isolation impedance is no longer within the recommended range. You may try running the IEEE PMA compliance tests to confirm the effect of using a different impedance.

Thank you,

Nikhil
