1.8V, 2.5V secondary oxide DDRx/LPDDRx PHY - TSMC 22nm 22ULP,ULL

Dolphin's hardened DDR2/3/4 SDRAM PHY and LPDDR2/3 SDRAM PHY IP is a silicon-proven, Combo PHY supporting speeds up to 2133 Mbps. It is fully compliant with the DFI 3.1 specification, and features include slew rate control, per-bit de-skew, gate training, read and write leveling and built-in self test (BIST). In addition, our PHY IP is optimized to provide a complete solution when combined with Dolphin's DDRx and LPDDRx SDRAM Memory Controller IP.
