EnterpriseAQRATE AQR205

Aquantia’s 28nm AQrate® AQR205 is the world’s only 2-port five-speed 10GBASE-T/5G/2.5G/1000BASE-T/100BASE-TX PHY in the industry.

The Aquantia 28nm AQrate PHY generation enables Enterprise Networking to evolve beyond 1G to 5G and 2.5G data rates through existing Cat5e and Cat6 cabling infrastructure. AQrate delivers 5G and 2.5G network connectivity speed through 100m of Cat5e or Cat6 cabling facilitating the unabated roll-out of 802.11ac WLAN infrastructure with zero change to legacy cabling. AQR205 integrates such features as Energy Efficient Ethernet (EEE), 1588v2, MACsec and supports all PoE standards up to 60W.

Wireless APs, compact switches, and myriad applications leverage low power of AQR205 to create passively cooled solutions. Its 19mm flip-chip BGA package features flexible system interfaces including full KR (with auto-negotiation) / XFI / RXAUI / XAUI / 2500BASE-X & SGMII.
