FCI disclosed that they have added a right angled receptacle to its AirMax VS (Virtual Shield) connector range, which, when combined with the existing right angled header, creates a "complete coplanar interconnect solution for Advanced TCA (ATCA) Zone 3."

The AirMax VS products previously announced include 3-, 4- and 5-pair headers and receptacles offered with a variety of IMLA column counts and spacings.

The 150 position Coplanar AirMax VS connectors are composed of 10 insert molded leadframe assembly (IMLA) columns, which each provide 5 differential signal pairs. As all signal lines and IMLAs are isolated from each other by air, interleaving shields are not required and insertion loss and crosstalk are minimized. The flexibility of the IMLA structure also means that column-to-column spacing within an AirMax VS connector can be adjusted to reduce the number of card layers and to further improve the electrical performance of interconnections while maintaining impedance at 100?.

Within the dimensional constraints of ATCA Zone 3, up to 4 Coplanar AirMax VS connectors can be placed side by side to provide a total of 200 high speed differential signal pairs.

In reference designs, FCI added, its connectors demonstrate excellent signal integrity at speeds from 2.5Gbps up to 6.25Gbps, and enable systems to be scaled to greater than 12Gbps without the need for a platform redesign.
