I am having a REALLY hard time finding multi-port RJ45 jacks with integrated magnetics that are compatible with a PHY using voltage-mode drivers. As I understand it, for the magnetics to be compatible the center-taps for each of the four differential pairs on the PHY side would have to be isolated from each other :
In nearly all of the modular jacks I am finding, the center-taps are connected together :
Am I missing something here? From what I can tell, voltage-mode TX drivers are not uncommon. Am I misunderstanding the magnetics requirements? Thanks.
