Networking switches and hubs in next-generation hyperscale data centers must support increased port density and higher data rates. In combination with increased processing power, system designers are leveraging the inherent advantages of direct mate orthogonal architectures when compared with traditional backplane systems.
Samtec supports orthogonal backplane architectures with new DMO options from within the ExaMAX® High-Speed Backplane Connector System.
Samtec ExaMAX® DMO Options
Samtec’s new ExaMAX® DMO solutions offer system designers flexibility by removing the mid-plane, allowing fabric cards and line cards to mate directly. This fast-growing system architecture increases airflow and improves thermal efficiencies throughout the chassis. DMO solutions enhance signal integrity via shorter trace lengths and fewer connector transitions while streamlining the system BOM and optimizing system cost.
Samtec’s ExaMAX® DMO system consists of the new EBDM-RA series which mates directly with existing EBTF-RA series. Currently both 6 pair x 10 column and 6 pair x 12 column solutions are available. Guide pin and screw mount options are also available. 6 pair x 6 column and 6 pair x 8 column options are under development.
“Next generation system designers are quickly adopting DMO architectures,” said Jonathan Sprigler, Backplane Product Manager at Samtec, Inc. “Leading equipment vendors from across the data center industry – storage, server, networking and other applications – are leveraging the advantages of DMO via Samtec’s new EBDM-RA series.”
Key ExaMAX® Technical Features
Samtec’s EBDM-RA series is but one solution from the ExaMAX® High-Speed Backplane Connector System. The ExaMAX® line of products is optimized for speeds up to 56 Gbps (PAM-4 modulation). Return loss compliance is achieved in both 85 Ω and 100 Ω systems due to targeting the 92 Ω specifications and controlling reflections at all geometry transitions within the connector.
ExaMAX® also has the industry’s lowest mating force with excellent normal force and meets Telcordia GR-1217 CORE specifications. With two reliable points of contact at all times, even when subjected to angled mating, residual stubs are minimized for improved signal integrity performance. A 2.4 mm contact wipe increases reliability while the hermaphroditic mating interface ensures stub-free mating and reliable alignment
The backplane system features individual signal wafers with differential pairs in a staggered design and arranged in columns with zero skew. Each wafer includes a one-piece embossed ground structure, which increases isolation to significantly decrease crosstalk.
