10/100/1000/10GBase Power/Circuit SMD Ethernet Transformer X5585999T7-F

Description:

Network transformers mainly have signal transmission, impedance matching, waveform repair, signal clutter suppression and high voltage isolation.
The role of the network transformer in the Ethernet is in the Ethernet device. When the RJ45 is connected through the PHY, a network transformer is added in the middle. Some transformer center taps are connected to the ground. When connected to the power supply, the power supply value can be different, 3.3V, 2.5V, 1.8V.
Some of the center taps are connected to the power supply and some are grounded. This is mainly determined by the type of UTP port driver used by the PHY chip. There are two types of drives, voltage drive and current drive. The voltage drive should be connected to the power supply; if the current is driven, the capacitor can be directly connected to the ground. Therefore, for different chips, the center tap connection is closely related to the PHY. For details, please refer to the chip's datasheet and reference design. The voltage to be connected to the power supply is determined by the level of the UTP port specified in the PHY chip data used.
