The DDR4/3 PHY is compatible with JEDEC DDR3 and JEDEC DDR4 SDRAMs, supports a range of DDR3 DRAM speeds from 666Mbps to 2133Mbps and DDR4 DRAM speeds from 1866Mbps to 2400Mbps, and target support x16 DDR3/DDR4 SDRAM components, the design include an analog hard macro (CLK/CMD/ADDR/DQ/DQS) and a synthesizable digital design. It supports software auto training includes read gate, read/write data eye timing, and PHY Vref settings. Supports DDR4/DDR3 SDRAM.
Optimized for high performance, low latency, low area, low power, and ease of integration, the DDR4/3 PHY is provided as a hard DDR PHY that is primarily delivered as GDSII including integrated application-specific DDR4/3 I/Os. Supporting the GDSII-based PHY is the RTL-based PHY. The DDR4/3 PHY includes a DFI 4.0 interface to the memory controller and can be combined with controllers for a complete DDR (Double Data Rate) interface solution.
DDR4/ DDR3 Combo PHY IP - 2400Mbps (Silicon Proven in UMC 28HPC+)
