電源管理是連接的關鍵

　　隨著網絡連接性向越來越多的設備普及，高速數據和高速電源的能力至關重要。動態電源的控制，特別是新的低電壓工作模式，要求設備對其總電源進行交互控制。這包括充電器和DC-DC轉換器的多個功率電平，當聯網接口被使用或閑置時。

　　將IEEE 802.3標準納入設計中，不僅影響了數據頭的設計，而且影響了整個設計，以處理峰值功率管理。本文將研究控制器集成電路和外圍設備，用于將現有設計改造為這些新標準。這些電源解決方案存在于嵌入式設計和系統級。

　　Need for power management

　　Networking products， unlike most computing equipment， fall into the infrastructure category. This means that the products and capabilities need to be accessible not only on a 24/7 basis but also in all locations. This need for 24/7 availability started when the utilization of the resources was also on a 24/7 basis. As computing has increased in speed and data rates have similarly risen， the networking devices no longer see a continuous flow of traffic. This packet-traffic-based flow impacts both the peak power utilization of the PHY for the network connections， as well as the baseline power response of the systems.
