1 XENPAK的输出电压控制XENPAK为10GBit/s以太网的光收发器模块的多源协议(MSA)。作为XENPSK MSA的一部分,XENPAK模块需要背板自适应电源(APS)作为输入,图1所示为APS和XENPAK模块的连接图。XENPAK模块的控制电阻(Control resister)设置APS的输出电压。表1列出了不同控制电阻下
1 The XENPAK output voltage controls the Multi-Source Agreement (MSA) of the XENPAK optical transceiver module with 10GBit / s Ethernet. As part of the XENPSK MSA, the XENPAK module requires backplane adaptive power (APS) as input. Figure 1 shows the connection between the APS and XENPAK modules. The XENPAK module’s Control Resister sets the APS output voltage. Table 1 lists the different control resistance
