BUSTRONIC'S NEW VXI BACKPLANE OFFERS SUPERIOR POWER DISTRIBUTION

FREMONT, California, Nov. 17, 2003 - Bustronic Corporation, an industry leading designer and manufacturer of high performance backplanes, continues to expand its VXI product offering. The new 11-slot VXI backplane from Bustronic features unique design techniques to provide the best power distribution in the industry.

Bustronic offers a custom, laminated busbar to distribute ±24V, ±12V, -5.2V, and 2V throughout the backplane, rather than the more common approach of bringing these voltages to the backplane at only one or two points. As a result of this technique, the Bustronic VXlbus backplane has one of the lowest voltage drops in the industry. It also allows for simplified cabling requirements since the power cables need only be connected to one point (for each voltage) on the busbar. Ground and +5V are distributed by standard, solid busbars. The use of 2 oz. copper power planes, four solid ground and two VCC planes, and distributed decoupling capacitors on all voltages helps provide the finest, most complete power distribution available.

The Bustronic VXI backplane line includes automatic active BUSGRANT and IACK jumpering, and a 4-point chassis ground that can be modified by the user to isolate the chassis ground from the digital ground. Ten-layer stripline construction provides superior performance, minimizes crosstalk, and provides for excellent RFI/EMI resistance. The use of computer simulation results in an optimized design with low DC resistance, low AC noise, and outstanding power distribution. The use of four signal layers (three for TTL and one for ECL) yields state-of-the-art results. A panel connector for SYS Reset, and a power monitor connector are optional. The VXI backplanes are compliant with VXIbus spec.Rev. 1.4, VMEbus C.1.

Bustronic currently offers 6U size "C" backplanes in 5, 6, 8, 9, 11, and 13 slots. Versions in the 9U size "D" configuration and custom versions are also available. The company also offers VXI test extender boards.
