When discussing networking controllers, often we deal with single chips that convert PCIe to Ethernet. With Thunderbolt, an additional TB controller is needed at either end, increasing cost and power. However now with mobile devices losing dedicated Ethernet ports, and the rise in professional docking stations, converting from USB to a Wired Ethernet solution is usually a common choice for users that work out of hotels or those that want to add simple Ethernet capability to a device without any. Rather than use a USB-to-PCIe controller, Aquantia is pushing forward with its new generation of USB-to-Ethernet chips designed to run at 5G and 2.5G speeds.
