Datasheet

Overview

The VIAVI Xgig 4-lane CEM-slot Interposer for PCI Express 5.0 (Xgig5P-PCIe5-X4-CIC) provides the connection between the VIAVI PCIe 5.0 Analyzer/Exerciser/Jammer platform and a system under test. It supports debug and verification of new ICs, new system hardware designs and FPGA firmware, validation of system BIOS and software, and manufacturing test.

The interposer installs into a 4-, 8- or 16-lane PCIe CEM slot of the kind found in many servers, workstations and desktop PCs. An endpoint card is inserted into the 16-lane slot connector on the top edge, creating the test data path, and cables connect the interposer to the VIAVI protocol analysis platform chassis. It operates at the PCIe 5.0 rate of 32GT/s across up to 4 lanes (bi-directional). The interposer requires an open chassis while in use.

Signal path

High-speed linear signal redrivers buffer system data signals across the interposer between the PCIe slot and the PCB fingers, so that a clean signal is delivered to the Analyzer and DUT devices for protocol capture and analysis. In Analyzer mode, DUT data is tapped from both the upstream and downstream paths as inputs to the Analyzer. In Analyzer/Jammer mode, the interposer data path is switched to route data into and out of the Xgig analysis system.

Power and software

Interposer power is independent of the host system and is supplied by an included external converter. The interposer is supported by the Xgig tool suite, including Trace Control, Expert and Serialytics, and works with the Xgig 5P16 and 5P8 analysis platforms.
