Xgig CEM Type-B, 16-lane Interposer Module for PCI Express 4.0

The VIAVI Solutions 16-lane CEM Type-B 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 a 16-lane PCIe CEM slot which is common on many servers, workstations, and desktop PCs. It operates at the 16GTps, PCIe 4.0 rate, across 16-lanes (bi-directional).

Highlights

• Supports link widths up to 16-lanes 
• Operates up to 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 
• A top edge 16-lane CEM slot connector accepts all endpoint DUT adapter cards 
• Bottom edge 16-lane PCB finger connector installs into host test system’s 16-lane PCIe slot 
• 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 error injection for deep system analysis
• Interposer power is independent of host system. A 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 16-lane Card Electro-Mechanical (CEM) specification 
• Size: 230mm deep x 185mm tall x 15mm thick 
• 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 Xgig4K-PCIe4- X16 Analyzer/Jammer chassis platform 

Benefits

• Provides consistent, repeatable capture of link training, equalization and other in-band and side-band data
