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

Provides a tap of host-system to M.2 PCIe SSD data signals for input to the VIAVI PCIe 4.0 Analyzer.

  VIAVI Solutions Xgig4K-PCIe4-X4-U2 is an Active Interposer optimized for developing, debugging and performance tuning NVMe SSD operation in highdensity 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. This interposer uses high-speed linear signal redrivers between host system and SSD devices-under-test. This design insures a clean signal is delivered to the Analyzer for reliable protocol capture and analysis.
