LPDDR3 178-ball Rigid BGA Interposer

Data Sheet 

Introduction

The Keysight Technologies, Inc. W3301A LPDDR3 BGA interposer enables probing of embedded memory LPDDR3 178-ball DRAM from the ball grid array with Keysight U4164A logic analyzers.

The W3301A LPDDR3 178-ball rigid BGA interposer is designed to capture data rates in excess of 1866 Mb/s.

Software

Default configuration for the W3301A interposer are included in the standard B4661A memory analysis software package. The Keysight B4661A memory analysis software provides four standard software features and four licensed memory analysis options.

B4661A standard software features

  •  Default configurations for DDR and LPDDR probing solutions for Keysight logic analyzers
  •  DDR setup assistant
  •  DDR eye finder/eye scan
  •  DDR configuration creator

The Keysight B4661A memory analysis software offers a suite of viewers and tools that include a protocol compliance violation testing capability across speed changes; a condensed traffic overview for rapid navigation to areas of interest in the logic analyzer trace; powerful performance analysis graphics; and DDR and LPDDR decoders. With the B4661A memory analysis software and a Keysight logic analyzer1, users can monitor DDR3/4 or LPDDR2/3/4 systems to debug, improve performance and validate protocol compliance. Powerful traffic overviews, multiple viewing choices, and real-time compliance violation triggering help identify elusive DDR/LPDDR system violations.

B4661A licensed software options

  •  DDR decoder with physical address trigger tool (Option-1NP/-1TP/-1FP)
  •  LPDDR decoder with physical address trigger tool for LPDDR/2/3 (Option-2NP/-2TP/-2FP)
  •  DDR and LPDDR compliance violation analysis toolset (Option-3NP/-3TP/-3FP)
  •  Post-process compliance violation analysis (Option-3NP/-3TP/-3FP)
  •  Real-time compliance violation analysis (Option-3NP/-3TP/-3FP)
  •  DDR3/4 and LPDDR2/3/4 performance analysis and ONFi analysis (Option-4NP/-4TP/-4FP) 

DDR eye finder and eye scan software

DDR eye scan results of LPDDR3 signals gives you qualitative insight for all signals relative to each other. LPDDR3 signals are scanned in groups (Clock, CS#, ADD&Command, READ DQ/DQS, and WRITE DQ/DQS).

DDR and LPDDR compliance violation analysis tool (B4661A-3FP/-3NP/-3TP) 

The DDR and LPDDR compliance violation analysis toolset provides two tools under one license: post-process and real-time compliance violation. Both compliance tools cover DDR, DDR2, DDR3, DDR4, LPDDR, LPDDR2, LPDDR3 and LPDDR4.

Key features of both the post-process and real-time compliance violation tools:

  • Test compliance violations across speed changes using the post-process compliance violation tool
  • Identify DDR/2/3/4 or LPDDR/2/3/4 state machine, protocol compliance and protocol level bus cycle timing violations using either post-process or real-time tools
  • Save time with automated real-time DDR2/3/4 or LPDDR2/3/4 protocol compliance measurements and trace captures using the real-time compliance violation analysis tool
  • Edit parameters of the DDR/LPDDR standard preset tests easily using the enhanced parameter editing interface for both post-process and real-time tools

Configuration Guide and Ordering Information

W3301A includes

  •  LPDDR3 178-ball rigid BGA interposer
  •  178-ball riser for devices under test that have components surrounding the LPDDR3 178- ball DRAM where the surrounding components are too close to install the W3301A without the riser. Riser includes a ground plane. Riser orientation is critical for proper operation.

W3301A requires

  •  Qty (2) E5406A Soft Touch Pro probes (each probe ships with a kit of 5 retention modules)
  •  Qty (4) U4201A cables to connect between the E5406A and compatible logic analyzer 1
  •  Qty (1) U4164A logic analyzer module 2, 3, 4 in a chassis with a host controller

Optional for W3301A

  •  178-ball riser for devices under test that have components surrounding the LPDDR3 178- ball DRAM where the surrounding components are too close to install the W3301A without the riser. Riser includes a ground plane. Riser orientation is critical for proper operation. Riser is included with the W3301A. – The 178-ball riser may be replaced with an optional 178-ball grypper socket
