Application:

USB 3.0 Multi-function Printer (MFP)

PLX Products:

USB338x Series – PCI Express to USB 3.0

Peripheral Controllers

Key Benefit:

Ultra Fast Printing and Scanning

The demand on higher printing speed, finer resolution and more

functionality has improved for multi-function printers (MFP) being since

they were introduced in the early 1990s. However, the connectivity to

computers has stayed at either the slower USB 2.0 (480Mbps) or the more

recent 1Gbps Ethernet, both of which are not able to keep up with the needs

of the growing job requirements.

With 50 page per minute (ppm) color printing speed and 1800dpi x 600dpi

resolution, a computer has to transfer uncompressed printing data at 2Gbps

to keep up with one of today’s fastest color MFP’s. That is more than 4X of

what USB 2.0 can deliver and more than 2X of today’s fastest connection

for printers.

USB 3.0: The Solution for the Next Five to Ten Years

The new 5Gbps bandwidth offered by USB 3.0 SuperSpeed is more than

10X of USB 2.0 Hi-Speed. At 5Gbps of transfer speed, an MFP will have

plenty room to improve printing speed as well as the speed for other

functions such as document scanning. All of

these high speed functions can work

simultaneously with the new bi-directional

communication of USB 3.0. The USB 3.0

standard has also added better power

management which can be controlled by

either the host or the peripherals on the bus.

This will allow the MFP to enter different low

power states depending on the idle time or

bus conditions.
