The symbols used for timing specifications herein follow the pattern of t
for inputs and t
full mode speed device timing (SFS) input (I) to go invalid (X) with respect to the clock reference (K) going to high (H). Also
t
going valid (V) or data output valid time. Note that, in general, the clock reference symbol representation is based on five letters
representing the clock of a particular functional. For rise and fall times, the latter convention is used with the appropriate letter:
R (rise) or F (fall).
Measured at capacitive load of 40 pF.
For reference only, according to the SD card specifications.
Average, for reference only.
