EnterpriseAQRATE AQR409

Aquantia’s 28nm AQrate® AQR409 is the world’s only 4-port three-speed 2.5G/1000BASE-T/100BASE-TX PHY in the industry.

The AQR407/AQR408/AQR409 are pin-compatible multi-speed 4-port PHYs housed in 19 mm flip-chip BGA packages enabling efficient high density design for high port-count and compact switches across a range of speed requirements.

The Aquantia® GEN2 AQrate PHYs are low-power, high-performance multi-speed 10GBASE-T/5GBASE-T/2.5GBASE-T/1000BASE-T/100BASE-TX transceivers. AQrate technology bridges the bandwidth gap between legacy Enterprise cabling infrastructure designed for 1 Gbps data rates and emergent 802.11ac WLAN technology aggregating 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 with zero change to legacy cabling.

AQrate PHYs are compatible with the NBASE-TTM Alliance PHY Specification, the recently ratified IEEE® 802.3bzTM standard and the IEEE® 802.3an standard to perform all the physical layer functions required to implement 10GBASE-T/5GBASE-T/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, MACsec and supports all PoE standards up to 60W.

AQUANTIA'S Enterprise Infrastructure MARKET SUCCESS


The development of the AQrate product line, based on the novel 5G/2.5G protocol invented by Aquantia, started in 2012 and led to the sampling of our first product in November 2013. This innovative product line was quickly adopted by Cisco and other major switching and WLAN AP OEMs in the ensuing months. As of Q3 2016, we are the only supplier in production with this Multi-Gig technology, which is compliant with the IEEE 802.3bz-standard.
