This means that data delay should be equal or less than the clock delay in the ideal case where
tSHSCLKL =10 ns:
tDATA_DELAY tCLK_DELAY < 10 6 4
tDATA_DELAY tCLK_DELAY < 0

High-Speed Write Meeting Hold (Minimum Delay)
The following equations show how to calculate the allowed skew range between the SD_CLK and
SD_DAT/CMD signals on the PCB.
tCLK_DELAY < tSHSCKL + tSHSKHOX + tDATA_DELAY tIH
Eqn. 13
tCLK_DELAY tDATA_DELAY < tSHSCKL + tSHSKHOX tIH
Eqn. 14
This means that clock can be delayed versus data up to 8 ns (external delay line) in ideal case of
tSHSCLKL =10 ns:
tCLK_DELAY tDATA_DELAY < 10 + 0 2
tCLK_DELAY tDATA_DELAY < 8

High-Speed Input Path (Read)
This figure provides the data and command input timing diagram.
Figure 31. High-Speed Input Path
For the input path, the device eSDHC expects to sample the data 1.5 internal clock cycles after it was
driven by the SD card. Since in this mode the SD card drives the data at the rising edge of the clock, a
sufficient delay to the clock and the data must exist to ensure it will not be sampled at the wrong internal
