Overview
The VIAVI Xgig 8-lane CEM-slot Interposer for PCI Express 5.0 (Xgig5P-PCIe5-X8-CIC) connects the VIAVI PCIe 5.0 Analyzer/Exerciser/Jammer platform to a system under test. It is used for debug and verification of new ICs, new system hardware designs and FPGA firmware, for validation of system BIOS and software, and in manufacturing test.
The interposer is inserted into an 8- or 16-lane PCIe CEM slot in the host system, a type of slot common on servers, workstations and desktop PCs. An endpoint card is inserted into the 16-lane slot connector on the interposer's top edge, creating the test data path. Custom data cables connect the interposer to the VIAVI protocol analysis platform chassis. It operates at the PCIe 5.0 rate of 32 GT/s across up to eight bidirectional lanes. The interposer requires an open chassis while in use.
Signal path
High-speed linear signal redrivers buffer the system data signals across the interposer, between the PCIe slot and the PCB fingers, so that a clean signal reaches the analyzer and the DUT for reliable protocol capture. 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, which allows error injection.
Software and power
Captured traces are handled by the Xgig tool suite, including Trace Control, Expert and Serialytics. The interposer is powered independently of the host system by an included external power supply.
