Tracewell Systems Inc. has combined extensive experience in high-density backplane production and high-frequency design. The result is a line of performance backplanes for VME64 Extensions 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 while maintaining a 6U overall height. Building on the success of Tracewell’s VME64 surface mount technology (SMT) backplanes, this all-stripline 10-layer design uses advanced SMT for termination, automatic daisy-chain and capacitive decoupling. This advanced design not only allows inboard termination for up to 21 slots but also single-sided surface mount assembly for improved reliability. The use of SMT on the Tracewell VME64 Extensions backplane dramatically reduces the inductance and capacitance associated with component leads, resulting in improved overall impedance and voltage characteristics. 

Optimized power and ground planes minimize voltage drop and ground shift, while eliminating the need for busbars. Single-point power connectors are positioned along the top and bottom edge of the backplane. Each connector is capable of up to 70 amps and may be rearranged to support most wiring requirements. A low-profile connector design allows wiring to be routed close to the backplane, providing clearance for rear plugging I/O boards and a 6U overall backplane height. Ground tracking in both J1 and J2 surrounds every signal line with a ground layer, lowers signal-induced noise, crosstalk, and IR losses. 

Tracewell 6U VME64 Extensions backplanes address the needs of high-technology computing applications for today and tomorrow.
