OpenVPX backplanes advance high volume throughput computing, says Atrenne

Gen-4 / Gen-5 OpenVPX backplanes have been designed for true signal integrity up to 25GBd. Atrenne Computing offers a range of standard and custom, high-performance backplanes, including 3U, 6U and hybrid 3U/6U models. These

Gen-4 / Gen-5 OpenVPX backplanes are designed to the signal integrity requirements of PCIe Gen4 and 100GbE and are claimed to offer the highest signal integrity (SI) in the industry.

Using 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, says Atrenne, adding that this is “a significant advancement 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,” said Jim Tierney, vice president defence and aerospace systems for Atrenne Computing Solutions.

The OpenVPX systems use VITA 46.30 MultiGig RT 3 connectors. Multiple backplane profiles are available, including pass-through backplanes. Atrenne also designs application-specific configurations to meet individual and custom requirements.
