USB 3.1 Hub Controller IP

Description and Features

USB 3.1 Hub controller is a highly configurable core and implements the USB 3.1 Hub functionality that can be interfaced with third party USB 3.1PHY’s. USB3.1 Hub controller core is part of USB3.0 family of cores.The core leverages GDA’s design expertise from its high speed interconnect family of IP’s including PCI Express, Serial Rapid IO and Hypertransport.

This Hub Controller core can be configured to support upto 15 downstream ports. This Hub Controller core supports all defined USB 3.1 power states. The design is carefully partitioned to support standard power management schemes. Optionally, it can be configured to manage power mode transitions of the controller and the USB 3.1 PHY for aggressive power savings required for bus powered hubs. The controller's simple, configurable and layered architecture is independent of application logic, PHY designs, implementation tools and, most importantly, the target technology.
