LPDDR BGA Probe Suited for Oscilloscopes, Logic Analyzers
Agilent Technologies introduced a low-power double data rate (LPDDR) ball grid array (BGA) probe for oscilloscopes and logic analyzers. The LPDDR BGA probe provides signal access points for LPDDR and mobile-DDR synchronous dynamic random access memory (SDRAM) for electrical, timing and protocol characterization. It is appropriate at the LPDDR and mobile-DDR BGA package ballout, which is defined by the Joint Electronic Device Engineering Council (JEDEC) in the JESD209A LPDDR SDRAM standard. This LPDDR BGA probe supports two SDRAM package sizes. The W2637A BGA probe supports the x16 SDRAM package, and the W2638A BGA probe supports the x32 SDRAM package. Embedded resistors in the LPDDR BGA probe provide desirable signal isolation between the signals on the system and the loading effect of oscilloscope and logic analyzer probes. Both probes are compatible with 0.8-mm ball-pitch SDRAM packages.
