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.
