This slide provides a list of terms used in this entire presentation. USB 3.0 is a USB standard that supports both 5 Gigabits SuperSpeed and the legacy USB 2.0. The USB Host directs data traffic and distributes power over the USB bus. As an example, a personal computer is a USB Host. A Device is a peripheral on the USB bus such as a USB disk drive or USB mouse. A note book or PC docking station with multiple USB ports functions is an example of a hub, a device that directs data traffic between a USB Host and multiple USB devices. The USB 3.0 Physical Layer, PHY, is a circuitry that transmits and receives USB data. It is important to note that a USB 3.0 PHY actually contains two PHYs; a SuperSpeed PHY and a USB 2.0 PHY. The upstream of a hub connects to a host or to a downstream port of another hub. The Upstream Port directs the upstream traffic from a device through the hub to the host. The Downstream Port of a hub connects to a device or an upstream port of another hub. Likewise, the downstream port of a hub directs downstream traffic, from the host through the hub to a device. A block diagram is provided on the slide to illustrate upstream and downstream port locations of a hub. A specification published by the USB Implementer’s Forum for charging portable USB devices, BC 1.2 allows up to 7.5 W for charging. This reduces charging time even further, and is standard USB 3.0 port. An ACA dock is a docking station that charges a device. The Apple Charging Standard is a specified battery charging standard for the iPhone, iPod, and iPad.
