Texas Instruments has introduced a PCI Express to PCI translation bridge which is intended to provide a migration path from conventional PCI to PCI Express.

The XIO2001 has its own Performance Tuning Tool which allows register settings within the bridge to be customised in real time using a graphical user interface (GUI) so that users can tune the bridge for their application.

The XIO2001 is available in a 7x7mm package.

An internal arbiter supports up to six downstream PCI bus masters, which will help in eliminating the need for external arbitration devices.

The XIO2001 integrates buffered clocks and built-in adaptive equalisation should improve jitter tolerance.
