USB338x: Easiest Way to Upgrade to
SuperSpeed USB 3.0
The PLX USB338x controller family provides a matching
bandwidth at 5Gbp/s between the PCI Express Gen 2 bus
and the USB 3.0 SuperSpeed bus. The controllers can
easily add a USB 3.0 client port to an existing PCI Express
system, as well as convert existing PCI Express functions
(endpoints) to a USB 3.0 product. The USB3380 can be
easily added to any PCI Express system as a simple PCIe
endpoint to provide a SuperSpeed USB 3.0 peripheral port.
The USB3382 provides one additional PCI Express port for
more connection flexibility. The internal high performance
switch of the USB3382 can configure the two PCI Express
ports into one x1 upstream plus one x1 downstream; one x2
upstream; two x1 downstream; or one x2 downstream port.
This flexibility allows different system configurations to
achieve the maximum performance of the product.
In a MFP design with no available PCI Express port, the
USB3382 can be used without a need of a PCI Express
switch by configuring one of its two PCI Express ports to
be an upstream port connected to the root complex, and the
other port to be downstream port connected to the other PCI
Express endpoint - such as a wireless LAN (WLAN)
adapter as shown in the following diagram.
As the successor of the gold standard NET2280 (PCI
to USB 2.0 peripheral controller), the USB338x can be
used with existing NET228x software with no or
minimal change. Driver stacks for the NET228x are
already available in common printer OS’s such as
Linux and VxWorks. Therefore adding USB 3.0
support in an existing driver stack is as easy as adding
the hardware by simply plugging the USB338x into
the system.
