Adding Hi-Speed USB 2.0 to Embedded PCI Designs
PLX Technology’s NET2280 PCI to Hi-Speed USB 2.0 Peripheral Controller is
designed for easy integration with existing PCI based systems and silicon. While
there are many PCI based USB Hosts on the market, the NET2280 is one of the only
PCI based USB Peripheral Controllers available. With the NET2280, adding a Hi-
Speed USB Device port is just a matter of connecting the PCI signals with the same
name together.
The PCI bus on the NET2280 can either be a PCI Host or a PCI Adapter. As a PCI
Adapter, the NET2280 can fit into any standard PCI slot (3.3 or 5 Volts). This
means that any system with a PCI bus can instantly add a USB 2.0 Peripheral Port in
minutes. As the NET2280 is supported by several operating systems, additional
software modification can be minimized.
As a PCI Host, the NET2280 can be used to convert existing PCI Cards or CardBus
Adapters to stand alone USB Devices or ExpressCard Adapters. Rather than relying
on a Host PC’s PCI Chipset, the NET2280 has a built-in CPU, to configure and bring
up a PCI device. Furthermore, the Auto-Enumeration Technology in the NET2280
allows the USB device to be enumerated by a USB Host without any interaction on
the PCI side.
Tuned for Performance
The NET2280 is designed for high performance transfers, with its USB port able to
match the bandwidth of most PCI chips.

Four mastering,
descriptor based
DMA controllers,
along with the
NET2280’s true
FIFO structure,
allow it to sustain
transfers of up to 40
Mbytes / sec.
Even at these
speeds, and the full
PCI bus running,
the low power
consumption of the
NET2280 allows
for its use in USB
Bus-Powered
devices.
