The I-Trac Backplane Connector System from Molex Inc. features a broadside-coupled, skew-equalized design that handles speeds up to 12.5+Gbps. The company says it offers several benefits over other backplane products including better impedance control, lower crosstalk and higher overall bandwidth.

Open pin-field design
The I-Trac System features an unique open pin-field design for greater flexibility to assign high-speed differential pairs, low-speed signals, as well as power and ground contacts anywhere within the pin-field. As a press-fit, mono-block system that can be stacked end-to-end to meet customer pin-count requirements, the I-Trac System is suitable for standard and orthogonal architectures in server, storage, telecommunications and data networking applications. In addition, the I-Trac System uses the same part numbers for both standard and orthogonal architectures by providing the option to rotate the headers 90 on one side of the midplane.

Another cost savings feature is the I-Trac System's support of quad trace routing, which reduces PCB layer count. Midplane PCB layers can be reduced even further by leveraging the orthogonal capabilities. In an orthogonal architecture, the I-Trac System completely eliminates the need for PCB traces through the use of shared vias.

Excellent mating performance
The I-Trac System also features integrated guidance options to ensure excellent mating performance versus non-integrated guided solutions. The I-Trac System power modules are capable of supporting over 250A of current per linear inch. The guidance, power and signal modules are designed to provide superior mating performance in the proper sequences based on each customer's unique application requirements, said the company.

Available in a variety of row and column sizes, the I-Trac System consists of backplane signal header modules and daughtercard signal modules. It is offered in standard 7-, 11- and 15-row versions, with a 5-row version planned for release in the near future. Module sizes range from 56 to 300 circuits.

Other tooled derivatives are also available, including a right-angle male (RAM) version for coplanar applications and a mezzanine version for parallel board-to-board, and reverse gender solutions.

An 11-row I-Trac backplane connector system is priced at 7 cents per mated line in volume. Lead time is six to eight weeks.
