11.3.2.1
High-Speed Read Meeting Setup (Maximum Delay)
The following equations show how to calculate the allowed combined propagation delay range of the
SD_CLK and SD_DAT/CMD signals on the PCB.
tCLK_DELAY + tDATA_DELAY + tODLY + tSHSIVKH < 1.5 × tSHSCK
tCLK_DELAY + tDATA_DELAY < 1.5 × tSHSCK – tODLY – tSHSIVKH
This means that Data + Clock delay can be up to 11 ns for a 20 ns clock cycle:
tCLK_DELAY + tDATA_DELAY < 30 – 14 – 5
tCLK_DELAY + tDATA_DELAY < 11
11.3.2.2
High-Speed Read Meeting Hold (Minimum Delay)
The following equations show how to calculate the allowed combined propagation delay range of the
SD_CLK and SD_DAT/CMD signals on the PCB.
0.5
× t
SHSCK < tCLK_DELAY + tDATA_DELAY + tOH – tSHSIXKH + tINT_CLK_DLY
0.5
× tSHSCK – tOH + tSHSIXKH – tINT_CLK_DLY < tCLK_DELAY + tDATA_DELAY
This means that Data + Clock delay must be greater than ~6 ns for a 20 ns clock cycle:
10 – 2.5 + (-1.5) < tCLK_DELAY + tDATA_DELAY
6 < tCLK_DELAY + tDATA_DELAY
11.3.2.3
High-Speed Read Combined Formula
The following equation is the combined formula to calculate the propagation delay range of the SD_CLK
and SD_DAT/CMD signals on the PCB.
0.5
× tSHSCK – tOH + tSHSIXKH < tCLK_DELAY + tDATA_DELAY < 1.5 × tSHSCK – tODLY – tSHSIVKH
