DP83822I: MDI controlled impedance reference

Roger Wilson

Part Number: DP83822I

Could someone confirm please, what the MDI 100R differential pairs (between the PHY and the magnetics) are referenced to? Is it Signal GND or AVD please?

Thanks,

Roger.

Hi Roger,

The 100 ohm differential routing is in reference to system ground.

Kind regards,
Ross
