The INNOSILICON DDR IPTM Mixed-Signal  DDR4/3/3L/LPDDR4/4X/3 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 DDR4/3/3L/LPDDR4/4X/3 SDRAM components in the  market. The PHY components contain DDR specialized functional and utility 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 72  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  DDR4/3/3L/LPDDR4/4X/3. 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.
