NEX-FBD-LAI-XX(B)

FBD (Fully Buffered DIMM) LAI (Logic Analyzer Interface) Interposers

New! Supports Tektronix TLA7BB4 modules.

The NEX-FBD-LAI-XX provides a quick and easy connection to interface a Tektronix logic analyzer to a 240-pin, FBDIMM.

The NEX-FBD-LAI-XX is an impedance controlled, matched trace-length interposer design and does not require a dedicated slot. The logic analyzer probes connect to ten, 24" cables for minimal mechanical interference.

Acquisition of FBD LAI mode data.

Impedance controlled / matched trace-length design.

Correlation with data from other acquisition modules.

NEX-FBD-LAI-XX is available in two formats.

The first format, NEX-FBD-LAI provides superior mechanical flexibility for tight fitting applications through its Rigid/Flex/Rigid design, edge-mount FBDIMM connector and probe connection points on the end of 24" cables.

The second format, NEX-FBD-LAI-RG provides a rigid only interposer solution.

FBD LAI Interposer Overview

FBD LAI interposers utilize the optional AMB LAI mode implementation described in the FB-DIMM Advanced Memory Buffer (AMB) Draft Specification. FBD LAI interposers utilize an AMB operating in LAI mode which repeats the FBD traffic to the FBDIMM plugged into the LAI. The LAI AMB also deserializes the FBD channel traffic and outputs that information in parallel form to logic analyzer probe points. This data is acquired, decoded and displayed by the logic analyzer.

For applications requiring monitoring of multiple FBD channels, each FBD LAI interposer comes standard with FBD Event Bus connectors which allow multiple FBD LAI interposers to be interconnected to enable triggering across multiple FBD channels.

An SMBus interface is also available on the FBD LAI interposer which provides the means for setting internal AMB trigger parameters. All hardware and software needed to set these parameters over a standard USB port are provided at no additional cost.

Please see the FBD AMB specification for more information on FBD LAI mode, the FBD Event Bus or the FBD SMBus communication link.
