NEX-DDR

DDR Interposer & Software

The NEX-DDR allows for acquisition of Address/Command, Read and Write Data of 184-pin, Unbuffered or Registered DDR 200 (or less) DIMMs. Supports PC1600 (DDR-200).

The NEX-DDR adapter is an impedance controlled, matched trace-length interposer design and does not require a dedicated slot. The logic analyzer connects above the normal DIMM height so that there is no interference with adjacent DIMMs.

Acquisition of DDR Address/Command, Read and Write data.

No added buffers to conceal system performance.

Impedance controlled / matched trace-length design.

2 GHz Timing analysis available on all DDR signals.

Correlation with data from other acquisition modules.

Selective Clocking stores data when Commands are present and for thirteen clock cycles after Column Address assertion, resulting in more DDR Bus Cycle activity and fewer Idle cycles stored in acquisition memory.

Simultaneous state and timing on every channel of the TLA.

Pre-defined Symbols for easy Trigger Setup for the following Command Cycles: Read Col Address Read, Write Col Address Write, Mode Register Set, Row Address Strobe, No Operation, Ignore Command Data, Burst Stop, Refresh, Precharge, and Precharge Select Bank.

System Requirements

• DDR 200MT/s Read and Write Acquisition Requires
  • TLA Application Software V3.2 or later
    • Two, merged, 200MHz state speed acquisition modules (TLA7L/M/N/P or Q)

Alternate configurations supported by this product allow for the acquisition of DDR read or write data can be found in the manual.
