The USB 2380 is a PCI Express Gen 1 (2.5Gbps) to USB 2.0 Hi-Speed
Peripheral Controller. It features one PCI Express Gen 1 x1 port and one
USB 2.0-compliant client port.
High Performance and Flexibility
The USB 2380 provides 480Mbps bandwidth between the
PCI Express Gen 1 bus and the USB 2.0 Hi-Speed bus. The controller can easily
add a USB 2.0 client port to an existing PCI Express system. The USB 2380’s
standard PCI Express interface provides a x1 upstream port to connect directly to
any PCI Express downstream port for maximum performance of the product.
Abundant Software
As the successor of the gold standard NET 2280, PCI to USB 2.0 Peripheral
Controller, the USB 2380 can be used with existing NET 2280/2282 software
with no change. Driver stacks are already available in common OS’s such as
Windows (XP, Vista, 7 and CE), Linux, and VxWorks. The USB Duet software
will provide the fastest PC interconnect at 480Mbps of transfer speed with just a
simple USB cable.

Target applications for the USB 2380 as a PCI Express endpoint include PCs,
servers, set-top boxes (STBs), digital video recorders (DVRs), printers, and PCI
Express embedded systems.
Add a USB 2.0 Client Port to PCI Express-Based Systems
The USB 2380 can be used to easily add a USB 2.0 client port to any PCI
Express based embedded system. As a PCI Express endpoint, the USB 2380’s
standard PCI Express interface connects directly to any PCI Express bus.

USB 2380, PCI Express to USB 2.0 Peripheral Controller
Standard PCI Express registers allow the existing Root
Complex to configure and send data to and from the USB
2380.
Software is already complete with Windows 7 Logo
certified and Linux drivers available for the USB Duet
file-sharing and networking functions. PLX provides a
turnkey hardware and software solution, which brings the
netbook with USB Duet Technology quick to market. For
more information on USB Duet Technology, visit

Development Tools
PLX offers hardware and software tools to enable rapid
customer design activity. These tools consist of a hardware
module (USB2380EVK), hardware documentation
(available at
www.plxtech.com),
and a Software
Development Kit.

Express based Printer with USB 2380
The USB2380EVK is a x1 PCI Express adapter board that
easily plugs into any standard PCI Express slot.
Both USB host and peripheral-side software is included
with the USB2380EVK. The host-side software consists
of USB drivers and test applications. The peripheral-side
firmware is used to configure the USB 2380 to resemble a
standard USB class device (like a printer or mass storage
device) for which no USB host drivers will need to be
written. For custom applications, firmware APIs are
provided to abstract the USB transactions to reads and
writes. While this software is available for various
operating systems, it is written in standard C with
portability in mind.

USB Duet Technology for Mobile PCs
The USB 2380 can be used to easily add a USB 2.0 client
port to a PCI Express based netbook architecture. The
hardware design is simple by connecting the PCI Express
signals to the PCI Express bus on the netbook chipset.
Adding a USB 2.0 client port to the netbook creates
innovative and killer applications for users, such as optical
disc drive sharing, instant file sharing, networking, and full
HDD/partition recovery, all over a simple USB cable
connection.
