Hi Team,

Do we have any SD buffer can support SD, (SDR104 mode) Bandwidth = 208MHz, 3.3V /1.8V, travel distance is 6000mil.

Thanks!

Hi Andrew,

We currently do not have a single device which can support the SD3.0 std speeds of 208Mhz. We do have other SD card solutions for lower speed of operation though. but in this case, we can suggest using sN74AVC2T45 for 2 channels ( CLK, CMD lines) and for the IO lines it would have to be another device.
