Overview
The VIAVI Xgig 16-lane CEM Interposer for PCI Express 5.0 connects the VIAVI PCIe 5.0 Analyzer/Exerciser/Jammer platform to 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 16-lane PCIe CEM slot, as found on many servers, workstations and desktop PCs, and an endpoint card is installed into its top 16-lane slot connector to form the test data path. It taps the data signals exchanged between host and endpoint devices and feeds them to the Analyzer chassis, operating at the PCIe 5.0 rate of 32GT/s across up to 16 bi-directional lanes. Custom cables connect the interposer to the VIAVI protocol analysis chassis. The interposer requires an open DUT system 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, delivering a clean signal to the Analyzer and DUT devices for protocol capture and analysis. In Analyzer mode, DUT data is captured from both the upstream and downstream signal paths. In Jammer or Analyzer/Jammer mode, the interposer data path is switched to route data into and out of the Xgig analysis system.
Power and mechanics
Interposer power is independent of the host system and is supplied by an included external converter. Exchangeable brackets allow secure chassis and endpoint card installation, and LEDs indicate power and operation status. The design follows the Card Electro-Mechanical (CEM) specification.
