Provides a tap of host-system to U.2 NVMe SSD data signals for input to the VIAVI Analyzer

Xgig U.2-Server, 4-lane Interposer for PCI Express 4.0

The VIAVI Solutions Xgig U.2-Server, 4-lane Interposer for PCI Express® 4.0 is an active Interposer optimized for development, debugging and performance tuning of NVMe SSD operation in high-density storage servers. Bidirectional PCIe 4.0 protocol data on 4 lanes is captured at 16GTps for analysis. The interposer supports either 1 link of 4 lanes, or 2 links of 2 lanes. It is compliant to the SFF-TA-1001 connections standard for PCIe signals.

Applications

  • Operates up to 16GTps, PCIe 4.0 data rates
  • Downward compatible with PCIe data rates of 2.5, 5.0 and 8.0GTps
  • Supports 1-link of 4-lanes, or 2-links of 2- lanes
  • NVMe SSD DUT (not supplied) plugs directly into the interposer
  • Data path uses high-speed linear redrivers to insure good signal capture with little or no tuning
  • Supplied with high-quality, custom SFF-8764 cables for analyzer system attachment
  • Supports side-band signal capture and triggering
  • Supplied power brick makes interposer power independent of host system
  • Works together with the VIAVI Xgig 4K4 and 4K16 PCIe 4.0 Analyzer/Jammer chassis
  • Supported by VIAVI Xgig Analysis tools for trace capture with flexible filters, triggers and more
  • Provides consistent, repeatable capture of link training, negotiation and other data
