概述 — CIE-USB4-2C-M1｜PCIe4.0 双口 USB4 Type‑C 扩展卡（视频输出）
PCIE-USB4-2C-M1 PCIe 扩展卡，为没有原生 USB4 接口的台式主板扩展双 USB4 Type‑C 接口，双向带宽最高 40Gbps。可搭配高速外置存储、雷电 4 外设、外置显卡坞以及 Type‑C 显示器使用，无需更换主板，即可升级主机高速接口。卡身采用 PCIe 4.0 x4 主机接口，支持 USB4 多协议隧道，包含 USB 数据隧道与 PCIe 数据包隧道，方便传输大容量原始媒体素材以及外置显卡渲染；向下兼容雷电 4、USB 3.2、USB 2.0 及老式 USB 设备，适配范围广。
视频输出依靠 DP Alt Mode 实现，需要使用配套 mDP 线从独立显卡连接至本卡才能传输画面。本卡仅支持数据传输、PCIe 隧道以及单路视频输出，不支持 PD 快充。扩展卡直接由 PCIe 插槽供电，无需额外外接供电线。
Engineered with a PCIe 4.0 x4 host interface, this card implements USB4 multi-protocol tunneling, supporting USB data tunneling and PCIe packet tunneling to facilitate large-volume raw media file transfers and external graphics rendering. It maintains backward compatibility with Thunderbolt 4, USB 3.2, USB 2.0 and legacy USB devices for broad interoperability. Video output relies on DP Alt Mode; you must connect the supplied mDP cable from your discrete graphics card to this card to enable display signal transmission. This card supports data transfer, PCIe tunnel and single-display video output only. PD fast charging is not implemented. The card draws its operating power entirely from the PCIe slot, requiring no separate auxiliary power cable.
