Overview
The DDR5-A-UDM-288 unbuffered dual-inline memory module (UDIMM) interposer enables probing of DDR5 UDIMMs with an oscilloscope.
- All major oscilloscope vendors supported
- 288-pin, UDIMM
- JEDEC Standard JESD79-5
- Easily access signals
- Small keep-out volume (KOV)
- S-Parameters for system simulation
- Oscilloscope de-embedding S-Parameters
- Add digital analysis using the DDR5-D-UDM-288 interposer
Midbus Probing
The DDR5-A-UDM-288 is a midbus probing solution. This enables complete signal access to the DDR5 bus for visibility and compliance analysis using a convenient UDIMM slot interposer. XH Series BGA interposers are also available for DDR5.
Simulation and De-Embedding
S-Parameters are included for target simulation and the creation of oscilloscope de-embedding filters.

Testing Services
The following services are available for this interposer.
Target Boot & Basic Functionality
For each target, this service will power on and ensure functionality of the target with the interposer(s) installed.
Add Digital Analysis
Add logic and real-time compliance analysis using a DDR5-D-UDM-288 interposer and a MA51x0 series logic analyzer.
M51x0 Series Analyzer & DDR5-D-UDM-288
A MA51x0 series analyzer and a DDR5-D-UDM-288 interposer enable protocol debug, compliance analysis and oscilloscope cross-triggering. With a turn-key setup, the MA51x0 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.
