New differential pair arrays (DPAM/DPAF series) from Samtec Inc. provide performance of up to a terabit per connector with up to 168 usable signal pairs. The signal pairs are provided on a staggered layout with perimeter grounds to reduce the overall number of grounds needed as well as to simplify signal routing on the boards.

The connector set features a 10mm mated height and solder-crimp tails for easier processing. The insertion and withdrawal forces of this array system are lower than most high-density connectors, according to the company. Final Inch data is available for 168-signal pairs. Other standard sizes available include 48- and 104-signal pairs.

Samtec's Final Inch reference designs address one of the most difficult design issues on the boardthe trace breakout region around high-speed connectors. These reference designs are free of charge to customers who specify and use Samtec's connectors.

Pricing for the DPAM/DPAF differential pair array system begins at 9 to 10 cents per mated line.
