The W4643A DDR4 2-wing BGA interposer for DDR4 x4/x8 BGA DRAM probing takes full advantage of the quad sample state mode on the U4164A. The W4643A is the smallest BGA interposers for DDR4 x4/x8 DRAM capable of capturing simultaneous read and write traffic at data rates exceeding 3.2 Gb/s. U4208A and U4209A probe/cables connect any W4640A Series DDR4 BGA interposer directly into the U4164A logic analyzer module from 61-pin high density zero insertion force (ZIF) connectors that attach to the W4640A Series BGA interposer wings.
The W4643A DDR4 x4/x8 BGA interposer allows signal access to the DDR4 signals critical to your debug and validation effort through a U4164A logic analyzer. The probe works in existing designs and eliminates the need for up-front planning or redesign. The probe connects directly to the balls of the DRAM or can be installed with DDR4 78 ball riser (included) or an optional 3rd party socket (not provided) enabling operation and acquisition of high-speed DDR4 signals.
