The paired MDI signals from the PHY to the magnetics in a GbE application
are each terminated by a 50R resistor and then together to a 10nF
capacitor
to GND. However some applications connect the 2 resistors to Vcc (2.5V) as
well. Can anyone explain why some configurations are like this and others
aren't? Is it something specific to the magnetics?
TIA,
Rog.
