Overview
The Synopsys DDR4 multiPHY is a complete physical (PHY) layer IP interface solution for PC/consumer and mobile ASICs, ASSPs, system-on- chip (SoC), and system-in-package applications requiring high-performance DDR4/DDR3/DDR3L/DDR3U/LPDDR2/LPDDR3 SDRAM interfaces operating at up to 2667 Mbps. The Synopsys DDR4 multiPHY is ideal for systems that require high DDR3/4 performance and also may require compatibility with
the latest mobile SDRAMs (LPDDR2 and LPDDR3) for chips targeting multiple applications with varying performance requirements.
Optimized for high performance, low latency, low area, low power, and ease of integration, the Synopsys DDR4 multiPHY is provided as a hard DDR PHY that is primarily delivered as GDSII and includes the application-specific I/Os. Supporting the GDSII-based PHY is the RTL-based PHY Utility Block (PUB) that includes PHY control features such as write leveling, data eye training, per-bit data deskew control, PVT compensation, and support for production testing of the DDR4 multiPHY. The DDR4 multiPHY includes a DFI 3.1 interface to the memory controller and can be combined with any of Synopsys’ universal memory or protocol controllers for a complete DDR interface solution.
