AQtion AQC111U & AQC112U

The Aquantia AQtion AQC111U and AQC112U are Universal Serial Bus (USB) to Multi-Gig Ethernet controllers that integrate a USB v3.1 Gen1 PHY and 5GBASE-T/2.5GBASE-T MAC/PHY in single-chip packages. These high-performance, small footprint devices enable low-cost, small form factor, docking stations and adapters for simple plug-and-play, Multi-Gig Ethernet network connection capabilities and are suitable for a wide variety of applications. They enable a new class of accessories for laptop users who want mobility combined with the reliability and performance of wired Multi-Gig Ethernet connectivity, when at their desks or on the road.

These new controllers enable perfect solutions for notebook users. The ubiquity of the USB connection also makes the adapters and docking stations based on the AQtion AQC111U and AQC112U suitable for use with desktops, game consoles, home gateways or any system with a USB 3.x port that would benefit from a high-speed network connection.

All AQtion controllers incorporate Aquantia’s AQrate PHY technology – which supports data rates of up to 5 Gbps – a USB host controller, and is also compliant with USB v3.1, v3.0, v2.0, and v1.1 specifications. These devices implement Multi-Gig Ethernet functionality with the AQC111U integrating a four-speed Ethernet PHY (5GBASE-T/2.5GBASE-T/1000BASE-T/100BASE-TX), while the AQC112U integrates a three-speed Ethernet PHY (2.5GBASE-T/1000BASE-T/100BASE-TX).


Aquantia AQtion AQC111U and AQC112U controllers are ideally suited for use in desktops, notebook PCs, ultrabooks, docking stations, game consoles, digital-home appliances, network printers, USB dongles, IP Set-Top Box (STB) and IP televisions, and virtually any embedded system that uses a standard USB port.
