The MicroSpeed SMT Connector for fast data transmission, was designed especially for board-to-board connections in telecommunications and data transmission devices. This new modular connector system is the right solution for next-generation systems with transfer rates of up to 10 Gbits/sec. For differential-data transmission several different signal-pair arrangements are possible. Parallel signal connections are recommended for improved crosstalk properties. We achieve exceptional signal integrity using a design which features two signal and two shield contact rows. SPICE models are available. Evaluation boards also can be borrowed or purchased.
