Xgig 5P8 is first eight-lane analyser for PCIe 5.0, says Viavi

Able to support link speeds up to 32Gtransfers per second, the Xgig 5P8 connects with other analysers for multi-protocol functionality and is claimed to be the industry’s first eight-lane version for PCIe 5.0.

It allows equipment manufacturers to ensure performance in accordance with the latest revision of the ubiquitous serial computer expansion bus standard, says Viavi.

The PCIe 5.0 standard doubles data capacity over a PCIe link to 32Gbits per second, per unidirectional channel, or greater than 1Tbit per second across the common 16-lane bi-directional slot interface. It has been developed to meet the performance demands of emerging bandwidth- and compute-intensive applications such as 400Gigabit Ethernet, IoT, hyperscale and artificial intelligence (AI).

Component manufacturers need test platforms that will validate performance according to the standard, while maintaining familiar user interfaces and management environments.

The Xgig 5P8 platform provides protocol analysis for PCIe 5.0 traffic at all layers of the protocol stack. It supports link widths up to eight lanes, and link speeds to 32Gtransfers per second. The Xgig 5P8 protocol analyser provides both PCIe and NVMe protocol analysis functions and backwards-compatibility to PCIe 4.0. For connects with other Viavi analysers with Ethernet, SAS, and FC interfaces to provide time correlated multi-protocol views.

The Xgig 5P8 chassis has 128Gbyte of memory and flexible allocation to capture and save multiple data traces. The chassis provides advanced PCIe and NVMe level trigger and search capabilities designed to speed debug and problem resolution time. Interposer auto-tuning simplifies and speeds system use, and enables repeatable capture results, adds Viavi.

Viavi provides network test, monitoring and assurance solutions for communications service providers, enterprises, network equipment manufacturers, government and avionics. It also specialises in light management for 3D sensing, anti-counterfeiting, consumer electronics, industrial, automotive, and defence applications.
