The Innosilicon DDR Mixed-Signal MCR-DDR5/DDR5/DDR4 PHY and controller provide turnkey physical interface solutions for ICs requiring access to JEDEC compatible MCR-DDR5 MRDIMM, DDR5 DIMM, and DDR4 DIMM devices. It is optimized for low power and high speed applications with robust timing and small silicon area. It supports all JEDEC MCR DIMM, DDR5/DDR4 DIMM components on the market. It also supports DDR5/DDR4 soldered-on-board devices. The PHY components contain DDR specialized high performance I/Os for utility and functionality, critical timing synchronization module (TSM), and low power/jitter DLLs with programmable fine-grain control for the aforementioned DDR device interface.
