Design Applications
USB Duet Technology
USB is ubiquitous today. This technology is most popular in
consumer devices and gadgets, such as digital cameras, flash
drives, mobile phones, and printers. USB Duet Technology
from PLX adds a USB client port (like on digital cameras) to a
mobile PC system and enables the port to have multiple
functions such as sharing files and peripherals. Its familiar
usage models (e.g. mass storage) and plug-and-play
capabilities allow instant usability.
The NET 2280 can be easily designed into the existing PCI
bus of all PCs. With its super low standby power (sub-micro
watts) and tiny FPBGA package (8x8mm), the NET 2280 is
ideal for any mobile platform. The NET 2280 the Gold
standard in the USB industry!
USB Duet Technology – USB Duet HD
USB Duet HD is a Mass Storage application using USB Duet
Technology. USB Duet HD allows for easy PC-to-PC file
sharing and PC migration through a USB connection. The PC
running USB Duet HD will look just like a USB Mass Storage
device (e.g. USB flash drive) to the Host PC. PLX provides
software to implement USB Duet HD on your PC design.
Add Hi-Speed USB 2.0 to a Printer
Another application for the NET 2280 is to add Hi-Speed USB
2.0 functionality to any PCI-based printer. The standard PCI
interface of the NET 2280 connects gluelessly to a printer’s
PCI bus backplane. Standard PCI registers allow the printer’s
CPU to easily configure and send data to and from the NET
2280.
The NET 2280 features six programmable USB endpoints for
any combination of Interrupt, Isochronous, and Bulk data
transfers. This allows printer applications to transfer different
data (such as diagnostic or critical print data) through different
endpoints to improve quality of service and ease of design.
PLX provides device firmware to configure the NET 2280 to
resemble a standard USB Printer Class device. With the USB
Printer Class firmware, these devices can be recognized by
PCs without any additional host-side drivers.
In these applications, the integrated CPU is usually not
needed.
The NET 2280 Reference Design Kit
The NET 2280 Reference Design Kit (NET2280EVB-LF) is a
PCI Adapter that easily plugs into any standard PCI slot (3.3V
or 5V).
Both USB Host and Peripheral side software is included with
the NET2280EVB-LF+CD. The Host side software consists
of generic USB client drivers and several test and
development applications. The Peripheral side firmware is
used to configure the NET 2280 to resemble a standard USB
class device (like a printer or mass storage device) for which
no USB Host driver will need to be written.
For custom, vendor-specific applications, the Firmware API is
provided to abstract USB operation to standardized function
calls. While this software is available for various operating
systems, it is written in standard C with portability in mind.
An included porting guide aids USB developers through the
entire porting process.
