JTAG
11.3.2.1
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.
This means that Data + Clock delay can be up to 11 ns for a 20 ns clock cycle:
11.3.2.2
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.
This means that Data + Clock delay must be greater than ~6 ns for a 20 ns clock cycle:
11.3.2.3
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.
