RJ45带变压器有哪些作用?
在以太网设备中,经过PHY接RJ45带变压器时,基地都会加一个网络变压器。有的变压器基地抽头接电源,有的又接电容到地。并且接电源时,电源值又能够不一样,3.3V,2.5V,1.8V都有。这个变压器的效果究竟是什么呢?
下面是一个大约的解答:
1、基地抽头为何有些接电源?有些接地?这个首要是与运用的PHY芯片UTP口驱动类型决议的,这种驱动类型有两种,电压驱动和电流驱动。电压驱动的就要接电源;电流驱动的就直接接个电容到地即可!所以关于不一样的芯片,基地抽头的接法,与PHY是有密切关系的,具体还要参看芯片的datasheet和参阅规划了。2、为何接电源时,又接不一样的电压呢?这个也是所运用的PHY芯片材料里规则的UTP端口电平决议的。决议的什么电平,就得接相应的电压了。即如果是2.5v的就上拉到2.5v,如果是3.3v的就上拉到3.3v。RJ45网络连接器
3.这个变压器究竟是什么效果呢,可不能够不接呢。从理论上来说,是能够不需要接变压器,直接接到RJ45上,也是能正常工作的。可是呢,传输间隔就很受限制,并且当接到不一样电平网口时,也会有影响。并且外部对芯片的搅扰也很大。当接了网络变压器后,它首要用于信号电平耦合。其一,能够增强信号,使其传输间隔更远;其二,使芯片端与外部阻隔,抗搅扰才能大大增强,并且对芯片增加了很大的维护效果(如雷击);其三,当接到不一样电平(如有的PHY芯片是2.5V,有的PHY芯片是3.3V)的网口时,不会对互相设备形成影响。RJ45连接器
总的来说,网络变压器首要有信号传输、阻抗匹配、波形修正、信号杂波抑制和高电压阻隔等效果。
