Texas Instruments Inc. (TI) disclosed that they have developed the first x1 PCI Express-to-PCI Bridge and PCI Express 1394a IC samples.

According to TI, the PCI Express 1394a IC enables one of the industry's first ExpressCard module that is based on PCI Express instead of legacy I/O. The new PCI Express devices, which TI demonstrated at the Intel Developer Forum (IDF) last week, helps desktop and notebook PC designers build easily adaptable, user-friendly products.

The new XIO2000 IC bridges an x1 PCI Express Bus to a 32bit, 33MHz/66MHz PCI Bus capable of supporting up to six PCI devices downstream. It supports full PCI Express rates of 2.5Gbps, and allows OEMs to design a split-chassis system that meets a user's ergonomic needs without compromising performance. The company said this will provide customers with PC form factors that are more user-friendly, placing I/Os that the user interacts with on a regular basis on the desktop while the system chassis is hidden from view. Additionally, this concept will allow OEMs to upgrade and differentiate platforms more effectively without modifying the main system board, helping to minimize desktop clutter.

The XIO2200 PCI Express 1394a device is a two port open host controller interface (OHCI) 1394a integrated link/physical layer device that interfaces to the PCI Express Bus. By replacing PCI Bus with PCI Express, the device eases the layout of a motherboard and can reduce cost. In addition, using the device in ExpressCard technology development allows designers to add 1394a support to PC and notebook computers through the ExpressCard slot, increasing end user capabilities such as digital video editing from a digital camcorder.

"1394a has extremely high adoption in the digital camcorder market," said Julie Holland, business manager for TI's connectivity solutions group. "As technology gains a greater foothold in the overall consumer electronics market, users will have the ability to connect their peripheral devices to their PC or notebook with a simple addition of an ExpressCard."

Both the XIO2000 and XIO2200 are already sampling, with volume production scheduled for the first half 2005.
