VIAVI Xgig 4K16 PCIe Analyzer.

Viavi demonstrates the ability of its Xgig test platform to support PCIe 5.0 specifications

  • Viavi Solutions has announced that its Xgig test platform can support the specifications of the PCIe 5.0 protocol.
  • This demonstration of protocol analysis of the 5th generation PCI Express data communication bus was conducted at the PCI-SIG Developers Conference held on June 18-19 at the Santa Clara Convention, California.

PCIe 5.0, the latest revision of the serial bus standard for expansion cards on a computer, doubles the transfer capacity on a PCI Express link to 32 gigabits per second per unidirectional channel or more than one terabit per second on the 16 channel bidirectional interface.

This doubling of speed meets the performance requirements of emerging bandwidth-intensive and processing-capacity applications such as 400 Gigabit Ethernet, IoT, Artificial Intelligence, and Hyperscale (very large scale computing, usually for Big Data and Cloud Computing purposes). Manufacturers of components for integrating next-generation IT equipment need test platforms to validate performance in accordance with the standard.

Viavi’s demonstration at the PCI-SIG Developers Conference is based on an evolution of the Xgig 4K16 analysis platform for PCI Express 4.0. It now allows detailed functional and performance analysis of the PCIe 5.0 protocol, supporting operation at 32 giga-transfers per-second.

The Viavi family of protocol analyzers meets the testing requirements of the PCIe 4.0 ecosystem. The Xgig 4K16 offers complete visibility into PCIe 4.0 traffic flows with advanced trace and analysis and jamming, supporting lane widths of x1, x2, x4, x8, and x16 at link speeds of 2.5 GT/s, 5.0 GT/s, 8.0 GT/s and 16 GT/s.
