DP83822IF: Electrical specification of MDI

Roger Newbould31

Part Number: DP83822IF

I have a question regarding the electrical specification of the MDI (media dependent interface) of the DP83822IF.

I assume that VOD is the differential output swing of TD, the signals going from the PHY to the SFP (FX mode).

What voltage swing is needed at the input to the PHY (RD)?

Hi,

100Base-FX Reciever voltage swing range is 0.3 to 1V

Thanks.

If I understood you correctly, the values in the lower table apply for Transmitter AND Receiver? I guess you mean 0.3V to 0.9Vpeak for FX?

Hi Roger,

Yes, your understanding is correct. Sorry for the writing it as 1.0V.
