Hi there, I am looking for the ideal GigE PHY. Power seem to be my problem in this circuit and I am looking into this right now. I recognized in a few datasheets that there are current numbers fpr analog and digital power supplies and in addition to that there is an entry called "center tap". That is then the center tap of the RJ45 Magnetics?! So what happens there and why is current drawn from the PHY to the center tap? When is this relevant? How is determined how much power is drawn to it.? One spec is also mentioning a dependency to a power class driver A/B. I dont have an appnote for that device (Marvell). Thanks a lot Rio.
