Atrenne’s New OpenVPX Backplanes Offer Industry-Highest Signal Integrity

Significant Advance in High Volume Throughput Computing

Atrenne Computing Solutions (a Celestica company) launched a new series of Gen-4/5 OpenVPX backplanes on 15 September.

The series is part of Atrenne’s innovative product family that enables end-to-end solutions for 64/100GB systems. The company offers a wide range of standard and custom, high-performance backplanes, including 3U, 6U and hybrid 3U/6U models. The Gen-4/5 OpenVPX variants are designed to the demanding signal integrity (SI) requirements of PCIe Gen4 and 100GbE (100GBASE-KR4), and offer the highest SI in the industry. By using full 3D electron microscopy (3D EM) field modelling in HFSS to develop highly accurate SI models, areas such as return loss, dielectric loss, skin effect loss and crosstalk have been stabilised in the backplane design – a significant advance in high volume throughput computing.

As sensor inputs and signal processing demands increase, so do the data rates of serial switched fabric protocols used for OpenVPX slot-to-slot interconnect planes,” explained Jim Tierney, VP Defense and Aerospace Systems. “Our internal testing and modelling research has helped us achieve robust Gen-4/5, 16/25’s Gbaud signalling in OpenVPX systems. Whether it is achieving greater performance through hi-speed backplanes or innovative cooling techniques, Atrenne delivers proven designs that accelerate innovation.”

The new systems operate on high performance VITA 46.30 MULTIGIG RT 3 connectors. Multiple backplane profiles are available, including pass-thru backplanes. Atrenne also designs application-specific configurations to meet individual and custom requirements.
