Overview

The Synopsys LPDDR5X/5/4X PHY is Synopsys’ physical (PHY) layer IP interface solution for ASICs, ASSPs, system-on-chips (SoCs) and system- in- package applications requiring high-performance LPDDR5X, LPDDR5, and LPDDR4X SDRAM interfaces operating at up to 8533 Mbps. With flexible configuration options, the LPDDR5X/5/4X PHY can be used in a variety
of mobile applications supporting LPDDR5X, LPDDR5 and/or LPDDR4X SDRAMs, precisely targeting the specific power, performance, and area (PPA) requirements of these systems.
Optimized for high performance, low latency, low area, low power, and ease of integration, the LPDDR5X/5/4X PHY is provided as hardened IP components (macrocells) to facilitate the following types of signals:
Single-ended Command/Address (C/A) and Data (DQ) signals
Differential signals (clock, data strobe, and WCK signals)
CMOS logic-level based C/A signals

Key features

  • Flexible channel architecture
  • 16- or 32-bit data path widths, supporting either a single 16-bit channel or two 16-bit channels
  • 64-bit SDRAM support, supporting four 16-bit channels via two 32-bit PHYs
  • Support for byte-mode DRAM devices for high-capacity systems
  • Support for many DRAM packaging options:
  • SDRAM components soldered directly to PCB
  • Package on Package PoP devices
  • PHY independent, firmware-based training using an embedded calibration processor
  • Utilizes specialized hardware acceleration engines
  • Supports:
  • Command Bus Training (VREF and Delay)
  • Write Leveling, Read Gate Training
  • Write/Read Training:
  • Per-bit DQS to DQ centering and per-bit deskew

  • Includes the PHY Utility Block (PUB)
  • Soft IP Verilog design that includes PHY control features, such as read/write leveling and data eye training
  • APB and JTAG interfaces for register access
  • Test support:
  • At-speed loopback testing on both the address and data channels
  • Delay line BIST
  • MUX-scan ATPG (stuck-at SCAN)
  • PLL lock test
  • ZQ calibration test
  • Facilitates a JTAG register interface for easy test access
  • Firmware-based 2D eye mapping diagnostic tool allows measuring 2D eye for every bit of the bus at both DRAM and host receivers
  • Direct override programming available for all VREF, ODT, drive strength, and timing delays to facilitate debug and characterization
  • Automotive grade PHYs in development
