UHS-II, SDHC and SDXC, 156MB/s Full Duplex 312MB/s Half Duplex, 4.00. UHS-III, SDH,in SD spec, SDR50 and SDR104 mode need to tunning the sampling point. That means the data width is 4-bit and the CLK frequency is 100MHz for SDR50 and 208MHz for SDR104. Considering the clock frequency, is the oversampling method suitable for the tunning , (6) SDR104: 1.8V signaling, Frequency up to 208 MHz, up to 104MB/sec. (7) DDR50: 1.8V signaling, Frequency up to 50 MHz, sampled on both clock edges, up to 50MB/sec. ※ Switch function command supports High-Speed, and future functions. ※ Correction of mem,SDR104: 1.8V signaling, Frequency up to 208MHz, up to 104MB/sec. - DDR50: 1.8V signaling, Frequency up to 50 MHz, sampled on both clock edges, up to 50MB/sec.
