PCI Express® 4.0 to U.2/U.3 Host Adapter
User Manual and Quick Start Guide
1
Introduction
Use this document for quick installation and setup.
Teledyne LeCroy's Gen4 U.2/U.3 Host Adapter provide a quick and simple means for test and debug of Solid State Drives
(SSDs) based on PCI Express (PCIe) protocols. They support data rates of 2.5 GT/s, 5.0 GT/s, 8.0 GT/s and 16.0 GT/s.
Each host adapter also supports side band signals such as PERST#, WAKE#, CLKREQ# and SMBus (SMBCLK, SMBDAT).
There are five different host adapter cards. All the adapters have similar features and only difference is how the links are
connected between the U.2/U.3 connector and the PCIe CEM Edge fingers:
Port A U.2 x4 Routing 4 lanes of port A from U.2 connector straight to the bottom PCIe CEM edge fingers.
Port B U.2 x2 Routing 2 lanes of port B from U.2 connector to the bottom PCIe CEM edge fingers (L0 and L1).
Port A U.3 x4 Routing 4 lanes of port A from U.3 connector straight to the bottom PCIe CEM edge fingers.
Port A U.3 x2 Routing 2 lanes of port A from U.3 connector straight to the bottom PCIe CEM edge fingers (L0 and L1).
Port B U.3 x2 Routing 2 lanes of port B from U.3 connector to the bottom PCIe CEM edge fingers (L0 and L1).

Perform to the following steps to connect each U.2/U.3 Host Adapter (see the sample image below):
1. Insert the U.2/U.3 device under test (DUT) through the 2.5" bracket making sure it connects properly in the top side of
the U.2 connector.
2. Make sure the power for the DUT is sourced correctly using switches SW4, SW7, and SW8. The factory default posi-
tions are SW5.1 OFF, SW5.2 ON, SW5.3 OFF, SW5.4 OFF, SW4 shunts 1-7, SW7 shunts 1-4, SW8 shunts 1-3. See
the tables below to source the correct power for the DUT.
3. Make sure only switch 2 from the DIP switch array SW5 is in the ON position. The PRSNT# pins configuration is x1 or
x4 device is selected using SW5 according to the table.
4. Plug the adapter with the device under test in any PCI Express slot.
5. Connect the power supply to the external power jack (J3) if needed.

Swapping the Full Height Bracket for the Half Height Bracket
Locate the two screws on the front of the Host Adapter securing the Full Height Bracket.
Using a Phillips head screw driver, remove the two screws that secure the full height bracket. Save the screws for installation of the half
height bracket.
