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 seve ral I/O devices; but they all c a n ’ t connect directly to the system PCI bus, so some kind of bridge is required. A 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.

Issue No. 14 Is There Enough Bandwidth with 32- bits/33MHz PCI? The 32-bit, 33MHz PCI bus allows a maximum throughput of 125MB/s, (or 1000Mb/s). Compare this with the maximum rates for USB 2.0 (480Mb/s), Firewire (400Mb/s) or 10/100 Ethernet (100 Mb/s). You can see there is plenty of bandwidth for the devices behind a 32-bit bridge like the PCI 6140. The PCI 6140 is Optimized for These Applications: ♦ PCI Latency-Sensitive Systems ♦ PCI-Retry Penalty Sensitive Systems ♦ PCI Slave Access Intensive Bridging Functions ♦ Low Power Systems ♦ CompactPCI Systems Using Hot Swap Lead Free Packaging available NOW! The PCI 6140 is available in lead-free, RoHS compliant versions as well as the traditional leaded packages.
