Overview

The DDR IP Mixed-Signal MR LPDDR4X/4/3/DDR4/3/3L Combo PHY provides turnkey physical interface solutions for ICs requiring access to JEDEC compatible SDRAM devices. It is optimized for low-power and high-speed applications with robust timing and small silicon area. It supports all LPDDR4X/4/3/DDR4/3/3L components in the market. The PHY components contain DDR-specialized functional and utility high-performance I/Os, critical timing synchronization modules (TSM), and low power/jitter DLLs with programmable fine-grain control for any SDRAM interface.

The comprehensive product portfolio also includes full GDS delivery, signal integrity and power integrity (SI/PI) analysis, verification models, prototyping support, and simulation tools. These offerings empower customers to accelerate development cycles, ensure robust performance, and stay ahead in the competitive landscape of high-performance memory solutions.
