Xgig U.2-Server, 4-lane Interposer Module for PCI Express 5.0

The Xgig® U.2-Server Interposer is optimized for development, debugging and tuning of NVMe SSD operation in high-density storage servers with U.2 connections
Xgig U.2-Server, 4-lane Interposer Module for PCI Express 5.0

The VIAVI 4-lane, U.2-Server Interposer for PCIe 5.0 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.

Benefits

  • Provides consistent, repeatable capture of link training, equalization and other in-band and side-band data
  • Faster analysis and problem isolation
  • Quicker time to market and earlier revenue
  • Lower engineering costs

Applications

  • Optimized for development, debugging and performance tuning of NVMe SSD operation in high-density storage servers
  • Used for IC development, debug and validation, subsystem and system-level testing, firmware and driver development and validation, and performance analysis
  • Works with VIAVI Xgig 5P8 and 5P16 PCIe 5.0 Analyzer/Exerciser/Jammer chassis

Highlights

  • Operates up to and including 32GTps, PCIe 5.0 data rates
  • Downward compatible with PCIe 1.0, 2.0, 3.0 and 4.0 data rates of 2.5, 5.0, 8.0 and 16GTps
  • 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 cables for Analyzer system attachment
  • Supports Analyzer side-band signal triggering and capture via custom cable
  • Supplied power brick makes Interposer power independent of host system
  • LEDs give quick indicators of power and status
  • Provides consistent, repeatable capture of link training, negotiation and other data
  • Supports error injection for deep system analysis
  • Supported by Xgig tool suite including Trace Control, Expert and Serialytics
