The W2637A, W2638A and W2639A LPDDR BGA probes allow you to get complete signal access to the LPDDR and mobile-DDR signals critical to your debug and validation effort with Keysight logic analyzers and oscilloscopes. The LPDDR BGA probes enable viewing of data traffic on industry standards LPDDR SDRAM, LPDDR NVM and mobile-DDR SDRAM. The probe works in existing designs and eliminates the need for up front planning or re-design. The probe connects directly to the balls of the DRAM, enabling you to operate at full speed and acquire high-speed LPDDR signals without impacting the performance of your design.

S parameter models are available for use with InfiniiSim for de-embedding purposes.

The LPDDR BGA probes also offer BGA probe sockets for easy probe attachment. Information on sockets is available at the following HSIO Technologies website.
