UHS2 Device Phy
Overview
This UHS2PHY 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. By using this unique SerDes technology, the UHS2PHY achieves 300MB/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.
