MAGJACK ETHERNET CONTROLLER DRIVER

Design 2 assumes the polarity can be different and makes sure non-IEEE No, it won’t make any difference. Since, the schematics shows center-tap on network side of the transformer and the Power Pins are brought out. It assumes the pinout and polarity as given on wikipedia. Design 2 gives your system more tolerance for miswiring, which is a good thing.

Ethernet magnetics are all pretty much designed to do the same thing, and the PHY will be designed to tolerate a wide range of cabling characteristics anyway, so the magnetics conyroller make little difference by comparison. The rectification designs that I am considering are given below: No, it won’t make any difference.

Design 2 assumes the polarity can be different and makes sure non-IEEE It appears to be designed to support PoE, given the way the center taps and extra pairs are brought out and labeled in the magjzck. The schematics presented in their datasheet has been posted below:.

I am having confusion in selecting the MagJack for the design. Design 1 is simplest and requires less space and components.
