Xgig CEM, 8-lane Interposer Module for PCI Express 4.0

Interposer Module for PCI Express 4.0 Platform

The PCIe4, 8-lane CEM-slot Interposer enables debug and verification of new ICs, system hardware designs, FPGA firmware, validation of system BIOS and software.
Xgig PCIe4 8-lane Interposer

The VIAVI Solutions 8-lane CEM-slot Interposer for PCIe 4.0 enables debug and verification of new ICs, new system hardware designs, FPGA firmware, validation of system BIOS and software—and supports manufacturing test. It provides connection between the VIAVI PCIe 4.0 Analyzer/Jammer chassis and a system under test. This Interposer installs into an 8- or 16-lane PCIe CEM slots common to many servers, workstations, and desktop PCs. It operates at the 16GTps, PCIe 4.0 rate, across 4-lanes (bi-directional). 

Highlights

  • Supports link widths up to and including 8-lanes 
  • Operates up to 16GTps, PCIe 4.0 data rates 
  • Downward compatible with PCIe gen-1, gen-2 and gen-3 data rates of 2.5, 5.0 and 8.0GTps 
  • A top edge 16-lane CEM slot connector accepts all endpoint DUT adapter cards 
  • Bottom edge 8-lane PCB finger connector installs into host test system’s 4-, 8- or 16-lane PCIe slot 
  • Supplied with four, high-quality SFF-8674 equivalent custom cables for Analyzer attachment
  • Data path uses high-speed linear redrivers to ensure good signal capture with minimal tuning 
  • Supports Analyzer side-band signal triggering and capture via custom cable 
  • Supports clock and trigger I/O
  • Interposer power is independent of host system. 
  • Power supply, 120/220 AC in, 12V/3A DC out converter is included 
  • Custom, exchangeable brackets enable secure chassis and endpoint card installations 
  • LEDs give quick indication of power and operation 
  • Format: Design is based on the PCIe Card Electro-Mechanical (CEM) specification 
  • Supports error injection for deep system analysis
  • Supported by Xgig tool suite including Trace Control, Expert™ and Serialytics™

Applications

  • Used for IC development, debug and validation, subsystem and system-level testing, firmware and driver development and validation, and performance analysis
  • Works together with the VIAVI PCIe4 Analyzer/Jammer platform chassis 

Benefits

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