5G POE Ethernet Lan Transformer For LED driver G4850CG with 48 Pins
Transformers:
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 current drive is connected to the
power supply; if the voltage 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.
Different voltages are required when connecting the power supply,
which is also determined by the UTP port level specified in the PHY
chip data used.
