Ventura high-speed, high-density connector

Teradyne Inc. Connection Systems Division (TCS) has unveiled its new Ventura high-speed, high-density connector, which the company claims to be the fastest single-ended interconnect with the most signal pins per inch of any connector available today.

The Ventura connector's unique platform allows it to be used in both 6.25Gbps single-ended, and 12Gbps differential applications. High-speed, single-ended electrical performance features crosstalk of less than five percent and insertion loss of less than 2dB at 6GHz and less than 3dB at 8GHz. Differential insertion loss is less than 2dB at 6GHz and less than 3dB at 10GHz.

The Ventura connector features 178 real signals per inch (single-ended) and 93 differential signals per inch in its 14-row version. Using surface-mount technology, the Ventura design reduces via effects and enables higher performance by replacing the standard compliant pin plated through hole with a 10-mil or 12-mil via, said the company. By using SMT, the company said it can place arrays with up to 5,000 contacts with 100% success at the solder joint.

In addition, the routing design of the Ventura connector permits very high-density signal routing in both horizontal and vertical directions in the backplane, which allows backplane designers to reduce printed-circuit-board layer counts while decreasing the time required to route the backplane. The Ventura platform currently includes 8-row and 14-row versions, as well as an 8-row right-angle male version.

The platform also includes connector backplane pins with a new stub-proof design and more than 2.5mm of wipe. Other features include a modular wafer design on both the backplane and daughtercard for maximum configurability, and a unique rear organizing stiffener for integration of power and guidance modules.

The Ventura connector is now available at approximately 18 cents to 24 cents per mated signal line in full production volumes.
