The INNOSILICON DDR IPTM Mixed-Signal LPDDR4/4X/DDR4/LPDDR3 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 LPDDR4/4X/DDR4/LPDDR3 SDRAM components in the market. The PHY components contain DDR specialized functional and utility SSTL 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 / LPDDR4/4X /LPDDR3. 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.
