Introduction

Teledyne LeCroy's PCI Express Gen4 x8 OCuLink Cable Interposer for the Summit™ PCI Express Protocol Analyzer product line provides

individual dedicated probes, making it easy to capture and analyze data traffic between a host and device that are connected using a

PCIe® OCuLink type cable based on the PCI Express OCuLink Cable specification. The PCI Express Gen4 x8 OCuLink Interposer taps

into the OCuLink point to point connection to allow an analyzer to capture and decode data traffic between two systems. It supports data

rates of 2.5 GT/s, 5.0 GT/s, 8.0 GT/s and 16.0 GT/s. The interposer assures reliable data transmission while providing 100% capture of

all data traffic flowing through the PCIe interface. Connecting the interposer to a Teledyne LeCroy analyzer allows analyzer to decode and

display data in both directions and across all lanes.

One PCIe OCuLink Cable can support PCIe link widths from x1 to x4. Larger links can be achieved by adding additional cables, e.g. a x8

link uses two PCIe OCuLink cables. The PCI Express OCuLink Specification allows in addition to in-band PCIe signaling the passage of

sideband signals such as PERST#, WAKE#, CLKREQ# and SMBus by passing them electrically through the link. The sideband signaling

(PERST#, WAKE#, CLKREQ#, SMBus and other functionality) can be monitored by the protocol analyzer through the interposer, where

protocol issues and performance metrics can be analyzed and debugged. RefClk signals external to the cable are also available on the

PCIe OCuLink Cable Interposer for use with the protocol analyzer.

The PCI Express Gen3 x8 OCuLink Interposer works with the PCIe OCuLink cable (or set of cables) up to 0.6 meter in length as defined

in the PCI Express OCuLink Cable specification.

3Connections

Perform to the following steps to connect the Interposer (see the image below):

1. Connect the supplied Teledyne LeCroy PCIe OCuLink Internal cable (PE017UCA-X) between the CH[0:3] port on the Root side of the interposer and

Port-0 of the OCuLink root. If x8 configuration is required, connect both Teledyne LeCroy PCIe OCuLink internal cables between the Root side ports

of the interposer and Port-0 and Port-1 of the OCuLink root.

2. If working in x4 configuration with an internal device, connect the second Teledyne LeCroy PCIe OCuLink Internal cable (PE017UCA-X) between the

CH[0:3] port on the Device side of the interposer and Port-0 of the OCuLink device. If x8 configuration is required use two off-the-shelf cables to con-

nect the End Point side ports from the interposer to Port-0 and Port-1 of the OCuLink device. If working with external devices you will need an off the

shelf 0.6m external cable.

3. Connect the Summit PCIe Gen 4 capable analyzer to the interposer as indicated in the diagram below.

4. Install the PCIe Protocol Analysis Software on the host machine. This application is needed to control the protocol analyzer.

5. Connect the analyzer to a host machine (where the PCIe Protocol Analysis Software application will be running) using the USB or Ethernet port on

the back panel of the Summit analyzer (or other compatible Teledyne LeCroy analyzer.

6. Connect 12V DC using the AC adapter supplied with the interposer. Make sure that the AC adapter is turned on.

7. Power on the analyzer.

8. Power on the host/root complex system.

9. Use the Teledyne LeCroy software application to monitor, record and view PCI Express traffic in the PCIe expansion card DUT system. Use Internal

Clock in the recording options tab of the application. In order to improve lock time for analyzer provide reference clocks for upstream and down-

stream and use External Clock option.

Note: Steps 6, 7, and 8 are needed in this order for power on traces.
