Xgig 16-lane CEM-slot Interposer for PCI Express® 4.0 

Provides data signal connection between a System-Under-Test and VIAVI Analyzer. 

VIAVI Xgig4K-PCIe4-X16-AI Active Interposer provides connection between the VIAVI PCIe 4.0 Analyzer/Jammer chassis and system under test. The Interposer installs into a PCIe CEM slot that is common on many servers, workstations, and desktop PCs. The Interposer provides a data signal tap of communication between host and endpoint devices. It operates at the 16GTps, PCIe 4.0 rate, across 16-lanes (bi-directional). This interposer uses high-speed linear signal redrivers to buffer the system data signals across the interposer between PCIe slot and PCB fingers. This design ensures a clean signal is delivered to the Analyzer for reliable protocol capture and analysis.
