Tracewell Systems has combined our extensive experience in standard architecture backplanes and high-frequency design. The result is a line of performance backplanes for VME that meet the needs of a wide-range of industrial, military, data and communication real-time applications. By utilizing the latest in design and manufacturing technology, Tracewell Systems provides a unique combination of performance, quality and value to its VME customers.

Tracewell 6U VME backplanes provide ideal signal and power distribution for both 32- and 64-bit applications. An all-stripline 8-layer design uses advanced surface mount technology (SMT) to maximize performance and reliability, while reducing cost to manufacture. Evolving out of a fundamental need for high-frequency performance, Tracewell VME backplanes utilize SMT to dramatically reduce the inductance and capacitance associated with component leads, resulting in improved overall impedance and voltage characteristics. Ground tracking, which surrounds every signal line with a ground layer, lowers signal-induced noise, crosstalk, and IR losses. By using SMT, ground tracking is possible even in the J1 section where it is most critical. Space optimized power and ground planes minimize voltage-drop and ground-shift, while eliminating the need for busbars to distribute power. Single-point power connections capable of up to 140 AMPS are user-configurable to support a range of wiring requirements. The existing backplane can also be assembled for fully passive applications as an option.

The Tracewell 6U VME backplanes address the needs of high-technology computing applications for today and tomorrow.
