The schematics presented in their datasheet has been posted below: Design 2 assumes the polarity can be different and makes sure non-IEEE Design 2 gives your system more tolerance for miswiring, which is a good thing.

The rectification designs that I am considering are given below: Since, the schematics shows center-tap on network side of the transformer and the Power Pins are brought out. Sign up using Email and Password.

However, It would be great if someone can comment on the designs for 4-pair mode. It assumes the pinout and polarity as given on wikipedia. I am having confusion in selecting the MagJack for the design.

The Ethernet part of the schematics is below: Ethernet magnetics are all pretty much designed to do the same thing, and the PHY will controllef designed to tolerate a wide range of cabling characteristics anyway, so the magnetics will make little difference by comparison. It appears to be designed to support PoE, given the way the center taps and extra pairs are brought out and labeled in the schematic. Design 1 is simplest and requires less space and components.

The schematics presented in their datasheet has been posted below:. R19 is unassembled My questions are: Design 2 will be similarly tolerant, and will work even if pairs are crossed over or otherwise mixed up.
