All Silicon IP


SLI PSDUHS2A_PHY is PHY IP solution for UHS-II interface that SD Association is working on the standardization as the new ultra high speed interface for both SDHC and SDXC. SLI s UHS-II PHY IP is most successful and sophisticated in the market. SLI has licensed 11products and 9 products are in mass production. By using SLI s unique SerDes technology, SLIPSDUHS2A_PHY achieves 312MB/s that is the maximum speed for UHS-II with the low power consumption. This PHY IP can be applied to both the device and host sides including SDIO and hence it can be utilized for SOCs for various applications including SD cards, digital cameras, digital videos, digital TVs, media players and personal computers.
