N2115A

N2115A is a DDR4 BGA interposer that provide signal access to the clock, strobe, data, address and command signals to the DDR4 BGA package for making electrical and timing measurements with an Infiniium oscilloscope. With the DDR4 JEDEC specification defined at the DRAM ballout, the BGA probe adapter provides direct signal access to BGA package for true compliance testing. The N2115A DDR4 BGA Interposers are soldered in between the DRAM and PC board or DIMM raw card where the DRAM would normally be soldered. They are designed with PCB or DIMM foot print on the bottom side and DRAM footprint on the top side. The signals from the memory controller chip and DRAM are then passed directly to the top side of the BGA probe adapter where they can be accessed with oscilloscope probes.

• Provides signal access for DDR4 DRAM x16 via JEDEC-standard BGA footprints to oscilloscope
• Solder-down test points allow signal access via logic analyzer leads or oscilloscope probe tips
• Effective bandwidth may be extended with InfiniiSim waveform transformation software
• Effective bandwidth may be extended with InfiniiSim waveform transformation software
• Supports InfiniiMax probes: E2677A, N5381A, and N5425A/N5426A differential solder-in heads
• S-parameter models are available for use with InfiniiSim for de-embedding purposes
