1.0 OVERVIEW 1.1 General Information The DDR3 Interposer Products are designed for ease of use. Interposers extra signal trace length, also an extra connector that might affect the quality of the system operation in some systems. • This Product is designed for capture of 1066MT/s or slower, and may only be used with the Tektronix TLA7BB4 acquisition modules. This product requires the use of the new NEX-PRB1X-T / PRB2X-T Low Profile Distributed probes available from Nexus

NEX-DDR3INTR-THIN Interposer products. This support can be used with Single Rank and Dual Rank DIMMs. Note that this manual uses some terms generically. For instance, references to the TLA700/7000 apply to all suitable TLA700/7000 Logic Analyzers, or PCs being used to control the TLA. NEX-DDR3INTR-THIN refers to the B_DDR3D_2D/2G/3A software support packages. Appendix G has a silk-screened print of the NEX-DDR3INTR-THIN Logic Analyzer Interposer board. Referring to this drawing whil

1.3 Eye size required The Eye size (stable data) required at the input resistor to the Nexus passive probes (NEX- PRB1X(-T) & NEX-PRB2X(-T)) is 330ps, and 0.2V. Capture accuracy may be affected if a stable eye can not meet this requirement. . The eye is a perfectly shaped diamond with each side equal distant from the center. 2.0 SOFTWARE INSTALLATION To Install the NEX-DDR3INTR-THIN software support place the B_DDR3D_XX Install CD in the CD drive of the TLA or the PC being us

3.5 Short “LEASH” probes The standard product includes 4 “LEASH” probes connected to this Interposer product. These short probes are soldered directly onto the interposer and interface the Interposer to the Passive probes that connect to the logic analyzer. These “LEASH” probes are to allow the user to easily install and remove the Interposer product in their system with out the added weight of the passive probe attached. There may be other probing options in the future. Contact Nexu

The strain relief on the LEASH to NEXPRB1X/2X interface, while designed for bench handling, can be damaged by twisting the coax cables. Bends of over 45 degrees in this area should be avoided. The coax connection points, under any circumstances, are not to be bent. 3.5.1 Samtec connector on the LEASH probe pins Figure 2 – Samtec connector on the LEASH probe The LEASH probe connects to the NEX-PRB1X-T or NEX-PRB2X-T probe using two plastic nuts and screws, with a plastic sp

3.6 Slot Numbering The Interposer must be installed in the furthest slot from the memory controller. For 1066MT/s support only the two furthest slots may be used. Slots are named as shown below: Slot naming for a three slot system Memory controller Slot C Slot B Slot A cS0-1# bS0-1# S0-3# cCLKE0-1 bCLKE0-1 CLKE0- (from NEX- (from NEX- PRBCOAX) PRBCOAX) If only one slot is used it must be the furthest slot from the memory controller.
