Teradyne Connection Systems Introduces the
GbX® L-Series Connector

Extends Product Family with High-Density, Lower Cost Solution

Nashua, N.H. – March 22, 2004 - Teradyne, Inc. (NYSE: TER) Connection Systems Division (TCS), the industry leader in high-performance connection systems, today announced the launch of its GbX® L-Series connector, which enables designers to easily create custom connector configurations to achieve specific performance needs and cost targets. The GbX L-Series connector is ideal for low-speed data lines and other sense and control functions, complimenting the high-speed capabilities of Teradyne’s successful GbX interconnect platform.

Designers can now co-locate GbX and GbX L-Series on the same connector to accommodate a mix of high and low-speed connections. Teradyne's GbX L-Series connector is an open pin field version of the GbX connector, and utilizes the same rear-organizing stiffener. The GbX L-Series connector is fully compatible with all GbX components such as power and guidance modules. By utilizing identical component features, the integrated GbX system eliminates many of the challenges and risks associated with mounting multiple connectors on a single card edge. Building all features and functionality required into a single integrated connector provides for a more reliable and efficient assembly.

“As system designers strive for higher bandwidth solutions at lower costs, they are also concerned about reliability,” said Bill Kenny, GbX L-Series project leader. “Teradyne’s GbX platform, including L-Series, is based on proven technology that delivers very high density and performance in mechanically robust packaging for exceptional reliability in the field.”

The 4 pair compatible GbX L-Series connector offers 151 signals per linear inch, with daughtercard wafers available in 5 column modules. Backplane modules are available in 5, 10, and 25 column configurations. GbX L-Series backplane modules are available in open configurations or with optional polarizing and guidance.

Pricing and Availability
Teradyne’s GbX L-Series platform connector is priced at approximately $0.04 - $0.06 per mated signal line in full production volumes and will be available in June 2004.

Demonstrations:
Teradyne will exhibit at DesignCon East 2004, April 5-7 in Boxborough, Massachusetts and at NepCon Shanghai, China, April 26-29, 2004.
