Original question:

DRA750: MMC1 timings in Default Speed Mode

DRA750: SD Card High speed Mode CLK frequency

MANOJ KUMAR K M
Prodigy 90 points

Part Number: DRA750

As per SD card standard the CLK frequency in high speed should be 50MHz, but in the DRA75x datasheet it is mentioned as 48MHz? could you please confirm it is correct value?

Because I'm using an SD card interface at MMC1, the SD card datasheet says its supporting clock frequency as 50MHz in high speed mode. So per standard the host should support 50MHz right?

Thanks

Manoj.
