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

This U.2-Server, version B Interposer is optimized for development, debugging and tuning of NVMe SSD operation in high-density storage servers

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

The VIAVI Solutions 4-lane, U.2B-Server Interposer for PCIe 4.0 uses high-speed linear signal redrivers to restore signal quality of the PCIe data lanes across the Interposer between host system and SSD devices-under-test. This Interposer enables debug and verification of new NVMe controller ICs, new system implementations, firmware, validation of system BIOS and software, and for manufacturing test quality assurance.

Highlights

  • Operates up to and including 16GTps, PCIe 4.0 data rates
  • Downward compatible with PCIe 1.0, 2.0 and 3.0 data rates of 2.5, 5.0 and 8.0GTps
  • Supports 1 link of 4 lanes, or dual-port operation of 2 links of 2 lanes each
  • Front-end module plugs into system-under-test
  • U.2 NVMe SSD DUT (not supplied) plugs into the Back-end module
  • Adjustable tray clamps and quick-release latch allow for snug fit and hot swap testing
  • Data path uses high-speed linear redrivers to ensure good signal capture with minimal tuning
  • Supplied with high-quality, custom SFF-8764 cables for Analyzer system attachment
  • Supports side-band signal triggering and capture
  • Supplied power brick makes Interposer power independent of host system
