  In Ethernet equipment, when the PHY chip is connected to RJ, a network transformer is usually added. The center tap of some network transformers is grounded. Some are connected to the power supply, and the power supply value can be different, including 3.3V, 2.5V, and 1.8V. Then how to connect the middle tap (PHY end) of the transformer? B. Why is it connected to a different voltage when it is connected to the power supply? This is also determined by the UTP port level specified in the PHY chip data used. The level must be connected to the corresponding voltage, that is, if it is 1.8v, it will be pulled up to 1.8v, if it is 3.3v, it will be pulled up to 3.3v.
