Intel® Ethernet Server Adapter 82575

Dual-Port Gigabit Ethernet server adapter designed for entry-level servers and Audio-Video applications.


       The new Intel®82575 Ethernet Server Adapter, builds on Intel's history of excellence in Ethernet products. Intel continues its market leadership with this newest generation PCIe* GbE network adapter. Based on the Intel® Ethernet Controller 82575, 

this adapter represents the next step in the Gigabit Ethernet (GbE) networking evolution for the enterprise and data center offering Audio-Video-Bridging (AVB) support, along with power management technologies such as Energy Efficient Ethernet (EEE) and DMA Coalescing (DMAC).


       • Low-halogen1 single-port PCI-Express* 10/100/1000 Ethernet adapter

       • Innovative power management features including Energy Efficient Ethernet (EEE), DMA Coalescing, ultra-compact design, 

         and a unique ventilated bracket for increased efficiency and reduced power consumption

       • IEEE 802.1Qav Audio-Video-Bridging (AVB) for tightly controlled media stream synchronization, buffering, and reservation

       • High-performing design supporting PCI Express* Gen 2.1 (2.5GT/s)

       • Reliable and proven Gigabit Ethernet technology
