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.
