c l a s s i c e x a m p l e i s t h e U S B

2.0/Firewire/Ethernet combo card shown

here. These low-end PCs and their add-

in cards are usually quite cost-sensitive,

and the standard PCI-to-PCI Bridge

from Intel adds too much to the BOM cost.

The Solution: Low-Cost Load Expansion with the

PCI 6140

On these PCI combo cards, there are normally two to four PCI devices

behind the bridge on the card. These PCI devices include USB, Firewire,

and Ethernet I/O chips as in this example; other combo cards include

RS 232, MIDI, SPDIF, TV Tuners, MPEG Decoders and Encoders,

Audio Processors, and other multimedia devices. The PCI Specification

allows each PCI slot only one device load. In order for multiple devices

to reside on the card, the PCI 6140 provides the lowest-cost isolated PCI

bus on its secondary. This bus can handle up to four PCI devices at

33MHz.

How many legacy PCs become useless

simply because they lack up-to-date I/O

connectivity? Sometimes all it takes to

bring new life to an old PC is to add

U S B 2 . 0 , F i r e w i r e o r E t h e r n e t

connectivity. This is easily accomplished

with a PCI Combo Card. A single add-

in card can have several I/O devices; but
