What are the functions of RJ45 with transformer?

The network transformer adopts T 1/e 1 isolation transformer, ISDN/ADSL transformer interface, VDSL high/low pass filter module, interface transformer, T 3/E 3, SDH, 64KBPS interface transformer, VDSL high/low pass filter module, interface transformer The working principle of the network transformer is to allow the signal of a certain frequency to pass through the repair (wave) smoothly, and to suppress the signal of another part of the frequency (noise suppression) , to match the impedance, and to isolate the voltage, the two are with lights RJ45 junction with transformers, from the appearance should be no difference. The specific difference is that the transformer line and pin are defined differently, based on the integrated RJ45 and primary center sub-ground circuit (75 ohm + high voltage capacitor, Bob-Smith connector) . The noise suppression ability of integrated design is stronger. Network transformers can also be designed according to customer needs. Function of RJ45 with transformer in Ethernet when Ethernet equipment is connected to RJ45 interface through PHY interface, a network transformer is added to the switch. Some transformers have central taps that connect to the ground. When power on, the power value can be different, 3.3 V, 2.5 V, 1.8 V. In high-speed applications, the requirements are becoming more stringent. For example, time mismatches and error message handling can occur when components in an electrical application do not work under the same clock. In these applications, the small time offset and/or noise of the clock signal significantly affects how the system interprets the signal.
