5-Speed 10GBase-T/NBASE-T PCIe Network Card This PCIe host card is based on Tehuti's new 3rd generation TN4010 controller and optimized 10 Gigabit Ethernet MAC designed for low-power, low-cost, single-port connectivity required by Application Servers and Workstations. The TN4010 MAC is paired with the AQrate AQR105 transceiver, a low-power, high-performance NBASE-T PHY. This card supports auto-negotiation allowing the NBASE-T solution to optimally select the best speed 10 Gigabit Ethernet 10GbE , 5 Gigabit Ethernet 5GbE , 2.5 Gigabit Ethernet 2.5GbE , 1 Gigabit Ethernet GbE or 100 Megabit Ethernet 100MbE over Cat5e/Cat6 or better cabling. Features Supports auto-negotiation for 10G, 5G, 2.5G, 1G, 100M Runs up to 10G at 100m with Cat6A cable or 2.5G at 100m with Cat5e cable Backward compatible with 1000Base-T, 100Base-T Networks PCI Express Gen-2 x4 host bus interface 16K Jumbo Frames IP, TCP, UDP checksum offloading IEEE 802.1Q Tagged VLAN Virtual NIC support Reduced CPU utilization and improved throughput Support Files User's Manual Jun 30, 2016 NBASE-T™ and AQrate are trademarks or registered trademarks and NBASE-T ALLIANCE℠ is a service mark of Aquantia Corp.
