PCI-E Card是规范“PCI Express Card Electromechanical Specification”的简称;通常,也将满足该规范的模组产品称为PCI-E Card,比如台式机上的内存条、声卡、显卡和网卡等模组产品。 PCI-E Card规范的电源输入为+12V和+3.3V两个,系统板Slot上能够提供的功率高达75W (12V, 6.25A),其上协议类型只支持PCI-E协议。
1. Modem and network card Wired or wireless expansion cards can be added to the motherboard via the PCIe x1 slot. A PCIe x1 WiFi card or a 1G PCIe Ethernet card can be connected to the PCIe x1 slot. Motherboards usually already have Ethernet built in. However, a PCIe x1 Wi-Fi card...
PCI Express architecture provides a high performance I/O infrastructure for Desktop Platforms with transfer rates starting at 2.5 Giga transfers per second over a x1 PCI Express lane for Gigabit Ethernet, TV Tuners, Firewire 1394a/bcontrollers, and general purpose I/O. PCI Express architecture ...

PCIE 1.0是最早发布的PCIE版本,于2003年引入。它基于电子行业协会(PCI-SIG)制定的第一版PCIE规范。PCIE 1.0的数据传输速率为2.5 Gbps(Gigabits per second),每条通道的带宽为250 MB/s(Megabytes per second)。此版本拥有一个x1通道,可通过插槽分配多个通道。
PCIe is a core technology used in many types of computer servers and endpoint devices. PCIe is scalable, and slots come in different configurations of bidirectional lanes: x1, x4, x8, x16, x32. The number represents the number of lanes in the PCIe slot. For example, a PCIe x1 slot prov...

每个Lane由两对差分传输对组成,一对用于发送数据,另一对用于接收数据,从而实现全双工(Full Duplex)通信。常见的PCIe通道配置包括X1、X2、X4、X8和X16,通道数量越多,数据传输速度越快。一个X1通道的实际带宽约为250MB/s(PCIe 1.0),而一个X16通道的带宽可以达到4GB/s(PCIe 1.0)。
PCIe is scalable, and slots come in different configurations of bidirectional lanes: x1, x4, x8, x16, x32. The number represents the number of lanes in the PCIe slot. For example, a PCIe x1 slot provides one lane and transmits data at 1 bit per cycle. A PCIe x2 slot provides two ...
先来看看PCIe针脚的定义。以PCIe x1为例,PCIe针脚分左右两块,左边负责供电,右边负载数据。 左边12V与3.3V从主板24pin取电,上限标准75W。PCIe额外供电为每6pin上限75W,每6+2pin上限150W。 右边根据插槽双面各数对针脚,A面一对收信号,B面一对发信号,各1bit。3.0速率8GT/s,因此3.0 x1带宽为单向8Gbps,双向16Gb...
