DIMM | Dynamic Termination | Protocol/Compliance
The DDR4-D-DIM-288 interposer enables probing of DDR4 DIMM (UDIMM, RDIMM or LRDIMM) with an MA41x0 series analyzer.
- Passive 288-pin slot interposer
- Unbuffered, Registered or Load-Reduced DIMMS (UDIMM, RDIMM, or LRDIMM)
- JESD79-4
- Address, Command, and Control probing with a MA41x0 series analyzer
Analyzers & Probes
A MA41x0 series logic analyzer / real-time compliance analyzer and a PRB-XL-1 probe is required to enable protocol debug, compliance analysis and oscilloscope cross-triggering. With a turn-key setup, the MA4150 can analyze thousands of real-time memory parameters across clock stops and frequency changes. Also includes 11ps x 10mV x 20-channel analog characterization (iCiS™) and dynamic probe termination.
Testing Services
The following services are available for this interposer family.
Target Boot & Basic Functionality
For each target, this service will power on and ensure functionality of the target with the interposer(s) installed.
MA4100: Signal Analysis & Basic Command Acquisition
For every channel on each interposer, this service will power on the target and place the target in a predefined state. A MAx150 series analyzer will then be connected to the target and the following tests will be performed and the following reports will be provided.
- iCiS eye analysis report of all command, address, and control signals, including recommended sampling positions and a MAx100 System Setup File.
- A real-time JEDEC protocol report including pass/fail for all basic protocol/sequence checks. Any failures will be noted in the report and an MAx100 Saved Session file will be provided so that the customer may review the results.
MA4100: Margin Testing – One Frequency
For a single channel each interposer, this service will power on the target and place the target in a predefined state. A MAx150 will be used to perform the following tests and the following reports will be provided.
- Real-time MRS/MRW to capture configuration information. On boot for targets running at one frequency. On boot and before a frequency change for targets that change frequencies.
- A real-time JEDEC margin test of one frequency. Any failures will be noted in the report and an MAx100 Saved Session file will be provided so that the customer may review the results.
MA4100: Additional / Custom Services
Additional and custom services may also be requested.
