背景技术Background technique

However, PCIE communication is not only used for data transmission between modules inside the server, but also for data exchange between inside the server and external devices. However, due to the limitations of the server space structure, it is impossible to integrate all PCIE interfaces on the CPU motherboard. Therefore, PCIE adapter cards are often used in server design to realize PCIE communication between the server and external devices.
现有技术中，专利号为201520556940.9的实用新型专利公开了一种支持线缆扩展的PCIE转接卡，通过对输入高速信号的相位进行补偿调整，来消除输入信号的随机抖动干扰，实现改善信号完整性，优化信号质量的功能，能满足服务器的扩展需求。但该方案并未实现PCIE设备热插拔与自动上电/掉电功能以及对设备在位信息的监测，性能较低。In the prior art, the utility model patent with the patent number of 201520556940.9 discloses a PCIE adapter card that supports cable expansion. By compensating and adjusting the phase of the input high-speed signal, the random jitter interference of the input signal is eliminated, and the signal is improved. Integrity, the function of optimizing signal quality, can meet the expansion requirements of the server. However, this solution does not realize the functions of PCIE device hot-swapping and automatic power-on/power-off, as well as the monitoring of device presence information, and its performance is low.
因此，提供一种高性能的多接口PCIE设备转接卡，是十分必要的。Therefore, it is very necessary to provide a high-performance multi-interface PCIE device adapter card.
