Boosting bandwidth with increased flexibility are two key advantages of Teradyne Inc. Connection Systems Division's (TCS) new GbX 2-pair connector. Designed for applications with tight slot constraints such as the blade server market, the new connector packs high performance in a small footprint. The new GbX version can also be used in dual-star applications where the line card differential pair density is low, or where routing to the connector in one or two layers is advantageous.

The GbX 2-pair connector features 27.5 real differential pairs per linear inch to fit compactly into a 15mm slot pitch. The GbX connector delivers excellent electrical performance and provides enhanced signal integrity with 100? matched differential impedance and crosstalk at less than 5 percent at a 50ps rise time (20 to 80 percent).

The GbX 2-pair connector features excellent routability out of the connector in one layer on backplanes and two layers on daughtercards, which reduces the number of signal layers required. An extra ground and an optimized footprint minimize crosstalk.

Scaleable for future system upgrades, the GbX connector's modular design allows for easy configuration and greater flexibility, and offers low-speed signals, as well as guidance and power modules. The unique stainless steel rear organizing stiffener and wafer construction is said to permit easy customization of daughtercard connectors using any combination of Teradyne's GbX product family and leverages proven technology for high levels of mechanical reliability.

In addition to the 2-pair configuration, the GbX product family includes 3, 4, and 5-pair versions with densities up to 69 differential pairs per linear inch, as well as power and grounded guidance modules. An L-Series version for low-speed signals is available in the 2-pair, 3-pair and 4-pair configurations. Used together, the connector platform meets different density requirements at the line and switch cards while maintaining the same signal integrity needs of the overall channel, said the company.

The GbX connectors are designed to meet European packaging standard IEC 917-2-2 International Standard, Part 2, Modular Order for the Development of Mechanical Structures for Electronic Equipment. In addition, the lower profile of the 2-pair GbX connectors allows for use of a smaller card pitch so more cards can be packed into a shelf, which is said to be important particularly in meeting European design standards for switches, routers and gateways.

Teradyne's GbX 2-pair connector is now available at approximately 12 cent to 18 cents per mated signal line in full production volumes for standard differential components.
