Receptacle enables coplanar interconnect solution

FCI has added a right angled receptacle to its AirMax VS connector range that combined with the existing right angled header creates a complete coplanar interconnect solution for AdvancedTCA Zone 3.

FCI has added a right-angled receptacle to its AirMax VS connector range which, combined with the existing right-angled header, creates a complete coplanar interconnect solution for AdvancedTCA Zone 3.

Supporting custom interconnects between the main card and direct mate rear transition module, the mated pair offers a signal line density of 25 differential pairs per linear centimetre of board length.

The 150 position Coplanar AirMax VS (Virtual Shield) connectors are composed of 10 insert moulded leadframe assembly (IMLA) columns, which each provide five 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 minimised.

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

In reference designs AirMax VS connectors demonstrate excellent signal integrity at speeds from 2.5 up to 6.25Gbit/s and enable systems to be scaled to greater than 12Gbit/s without the need for a platform redesign.

The flexibility of the IMLA structure 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 100ohm.

AirMax VS products previously announced include three-, four- and five-pair headers and receptacles offered with a variety of IMLA column counts and spacings.

Future product introductions include AirMax VS modules that incorporate FCI's patented BGA connector termination technology.
