PCI Express® 2.0 Active Interposer with CLKREQ# and SRIS Support

Active Interposer

175 mm Allows Reliable (6.7”) Probing of PCI Express Traffic with Quick, Simple Setup!

Specifications The Teledyne LeCroy Gen2 Active Interposer with CLKREQ# and SRIS support provides an economical means to probe PCI Express traffic Dimensions 175 x 168 mm between a host and PCIe® expansion card. The interposer assures (6.7” x 6.2”) reliable data transmission while providing 100% capture of all data Link Width x1, x4 or x8 traffic flowing through the PCIe slot interface. Connecting the interposer to a Teledyne LeCroy analyzer allows decoding and display of data Data Rates 2.5 GT/s (Gen1) flowing in both directions and across all lanes, and will display data and 5 GT/s (Gen2) traffic using the industry-standard CATC Trace™ data display, along with a wide range of traffic and error reports. Ordering Information The Gen2 Active Interposer with CLKREQ# and SRIS supports data Product Description Product Code rates of 2.5 and 5.0 GT/s (Gen2). Lesser lane widths are also supported (e.g., the x8 configuration supports x4, x2 and x1 through the Active G2x8 Interposer Kit PE110UIA-X x8 PCIe connector mounted on the card, but cannot support greater with CLKREQ# and SRIS than x8 since the host connector is limited to x8). The interposer can be includes Interposer, iPass Y-Cable, used with host PCIe expansion slots as small as x1 by using card edge x1 and x4 edge adapters reducer adapters (see diagram on following page—again, the Compatible Protocol Analyzers* connection will automatically negotiate to the lowest lane width). Summit T28 (licensed as a PE070AAA-X The Gen2 Active Interposer with CLKREQ# and SRIS support, in Gen2, x8, no probes/cables) combination with a Summit™ protocol analyzer, provides the user a *or other Teledyne LeCroy Summit protocol analyzer complete suite of test capability, including the ability to test products to the PCIe 3.0 specification at data rates up to 5 GT/s, and allows testing of new low power modes supported through CLKREQ# and SRIS. The new Gen2 Active Interposer with CLKREQ# and SRIS support is a powerful and versatile tool for all developers working with Gen2 PCIe expansion cards. Gen2 x8 Active Interposer with CLKREQ# and SRIS Interconnection Overview

Host PCIe Slot

Connecting the Gen2 x8 Active Interposer with CLKREQ# and SRIS 1. Install the Interposer into the host system PCIe connector, using a card edge reducer adapter if needed (for x4 and x1 PCIe slots only). 2. Install the PCIe expansion card under test (DUT) into the connector on the interposer. Note that PCIe expansion cards with edge connectors up to x8 can fit the connector on the interposer, but if x4 or x1 expansion cards are inserted, the connection will negotiate to the lesser lane width. 3. Connect 12V DC using the AC adapter supplied with the interposer. Make sure that the AC adapter is turned on. 4. Connect the Summit T28 Analyzer (or other compatible Teledyne LeCroy analyzer) to the interposer using the iPass Y-cables, as indicated in the diagram above. The “A” connector goes to “Upstream”. 5. If testing SRIS, refer to the clock configuration tables in the manual to properly select the clocks. 6. Connect analyzer to host machine using either the USB or Ethernet port on the Summit analyzer. System Compatibility 7. Install the software on the host machine. Summit T3-16  Summit T3-8  8. Power on the analyzer, then power on the host PCIe system. Summit T34  9. Use the Teledyne LeCroy software application to monitor, record and view PCI Express Summit T28 traffic in the PCI expansion card DUT system. Summit T24 
