EnterpriseAQRATE AQR809

The Aquantia® AQrate® AQR809 is the world’s only octal-port, multi-gigabit (2.5GBASE-T/1000BASE-T/100BASE-TX) Ethernet PHY in the industry. AQrate technology enables higher speed connectivity for client systems like workstations, PCs, NAS and new 802.11ac WLAN access points, bridging the bandwidth gap between legacy Enterprise cabling infrastructure designed for 1 Gbps data rates and new applications that demand bandwidth in excess of 1 Gbps. AQrate delivers 5 GbE and 2.5 GbE network connectivity speed through 100 meters of Cat 5e or Cat 6 cabling enabling the unabated roll-out of 802.11ac WLAN infrastructure and other new use-cases with zero changes to legacy cabling or infrastructure.

AQrate PHYs are compatible with both the IEEE 802.3bz standard and NBASE-TTM Alliance PHY Specification to perform all of the physical layer functions required to implement 2.5GBASE-T/1000BASE-T/100BASE-TX® transmission over 100 meters of twisted pair cabling. The AQrate PHY family integrates such features as Energy Efficient Ethernet (EEE), 1588v2, and MACsec, and supports all PoE standards up to 100W.

The AQR809 is a multi-gigabit, 8-port PHY housed in a compact 23 mm flip-chip BGA package enabling the most efficient high-density design for high port-count and compact switches.
