SD card and eMMC Transceivers for 1.8V

Do we need to have transceivers if we support 1.8V IO level on FPGA ? Doesn't have the capability to support the 1.8V ? And also it requires the PU to 3.3V on these interface. ​Are these mandatory ...

​So for eMMC this trancievers are not required right ? because this voltage doesn't change as SD card . So 1.8V emmc device should work .

Hi,

If the operating voltages are both 1.8V as mentioned, external transceiver are not required.

Regards.
