PE048UIA-X XMC Gen2 x8 Interposer
Card for Summit T2-16
and Summit T3-16
The LeCroy Gen2 XMC Interposer Card allows users to connect a LeCroy
PCI Express Analyzer between a VITA 42.3 (XMC) mezzanine module and
the carrier board. The analyzer can be used to capture, decode and display
all traffic on the PCI Express bus for troubleshooting, debugging and
monitoring system performance.
Installation is quick and simple: The interposer card is plugged into the
card slot in place of the XMC module, the XMC module is plugged into the
interposer, and the analyzer is connected to a separate connector on the
interposer card.
The XMC Interposer Card supports PCI Express lane widths up to x8 at
data rates of 2.5
GT/s and 5 GT/s. The card supports an analyzer
connection to LeCroy Summit T28, T2-16, T3-8 or T3-16 Analyzers.
XMC (VITA 42) expands the existing PMC standard by adding switched
fabric interconnects and adds new connectors (Pn5 and Pn6) that are
specifically chos
sen to support high-speed differential signals for fabrics or
user I/O.
LeCroy is a strong supporter of embedded board communication and
provides advanced tools for rapid product development and debugging of
new XMC products.

Connecting the XMC Interposer
1. Set the DIP switches on the XMC Interposer to the correct
setting for the lane width desired (x1, x2, x4 or x8) and for the
desired Ref Clock Inputs (if used).
2. Install the XMC Interposer into the XMC Backplane or Slot.
3. Install the XMC Device Under Test (DUT) into the XMC
Interposer (on backside).
4. Connect 12V DC using the AC adapter supplied with the
interposer. Make sure that the adapter is turned on.
5. Connect the Summit T28 Analyzer (or other LeCroy PCI
Express analyzer) to the XMC Interposer.
6. Connect the analyzer to a host computer system using the
USB 2.0 port on the rear panel of the Summit T28 analyzer.
7. Install the software on the host system.
8. Power on the analyzer.
9. Power on the XMC system.
10. Use the LeCroy software application to monitor, record and
view PCI Express traffic in the XMC system.
