DDR PHY

Overview

DDR5, DDR4, DDR3 PHY

The DDR solutions, a family of high-speed on-chip interface IP, are leading the way for high-performance computing (HPC) systems and data center applications. The DDR PHY IP is engineered to quickly and easily integrate into any system-on-chip (SoC) and is verified with the Denali DDR Controller IP as part of a complete memory subsystem solution. Available as a product optimized solution for specific applications such as DDR5, DDR4, DDR3 with many configuration options to select desired features and integration aspects.

Key Features

  • DDR5/4/3 training with write-leveling and data-eye training
  • Optional clock gating available for low-power control
  • Internal and external datapath loop-back modes
  • I/O pads with impedance calibration logic and data retention capability
  • Programmable per-bit (PVT compensated) deskew on read and write datapaths
  • RX and TX equalization for heavily loaded systems
