tCLK_DELAY + tIH tSFSKHOX < tSFSCKL+ tDATA_DELAY
Eqn. 5
This means that clock can be delayed versus data up to 15 ns (external delay line) in ideal case of
tSFSCLKL =20 ns:
tCLK_DELAY + 5 0 < 20 + tDATA_DELAY
tCLK_DELAY < 15 + tDATA_DELAY

Full-Speed Write Combined Formula
The following equation is the combined formula to calculate the allowed skew range between the
SD_CLK and SD_DAT/CMD signals on the PCB.
tCLK_DELAY + tIH tSFSKHOX < tSFSCKL + tDATA_DELAY < tSFSCK+ tCLK_DELAY tISU tSFSKHOV
