The INNOSILICON DDR IPTM Mixed-Signal  LPDDR5/5X/4/4X Combo PHYs provide 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 JEDEC LPDDR5/4 SDRAM components in the market. The PHY components  contain DDR specialized functional and utility high performance I/Os, critical  timing synchronization module (TSM) and a low power/jitter DLLs with  programmable fine-grain control for any SDRAM interface.

Note that all INNOSILICON PHY is  pre-assembled with.lib, LEF and GDS so that it is very easy to integrate the  PHY with any existing SoC floor plan. DDRn bus width can be from 4 bit to 80  bit or more. INNOSILICON is happy to pre-assemble each PHY for our customer so  that integration becomes extremely easy.

The combo PHY solution includes DDRn controller and PHY, supporting  LPDDR5/5X/4/4X. With configurable timing and driving strength parameters to  interface to the wide variety of SDRAMs, the PHY is very flexible with advanced  command capability to increase SDRAM operation efficiency.
