The Universal Flash Storage (UFS) standard has rapidly become the backbone of high-performance mobile computing. From flagship smartphones like the Samsung Galaxy S23 to automotive infotainment systems and professional drones, UFS 3.1 offers sequential read speeds exceeding 2,100 MB/s—dwarfing the capabilities of eMMC. The 26 MHz reference clock from the host
The 26 MHz reference clock from the host (SoC) to the UFS chip. Without this, the chip cannot synchronize. Measure for a clean sine wave (0–1.8V). Missing clock = dead UFS.
