Notes
1. The symbols used for timing specifications herein follow the pattern of t
(first three letters of functional block)(signal)(state) (reference)(state)
for inputs and
(first three letters of functional block)(reference)(state)(signal)(state)
for outputs. For example, t
FHSKHOV
symbolizes eSDHC
high-speed mode device timing (SHS) clock reference (K) going to the high (H) state, with respect to the output (O) reaching
the invalid state (X) or output hold time. Note that in general, the clock reference symbol 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).
2. In full-speed mode, the clock frequency value can be 0-25 MHz for an SD/SDIO card and 0-20 MHz for an MMC card. In
high-speed mode, the clock frequency value can be 0-50 MHz for an SD/SDIO card and 0-52 MHz for an MMC card.
3. To satisfy setup timing, one-way board-routing delay between Host and Card, on SDHC_CLK, SDHC_CMD, and
SDHC_DATx should not exceed 1 ns for any high speed MMC card. For any high speed or default speed mode SD card, the
one way board routing delay between Host and Card, on SDHC_CLK, SDHC_CMD, and SDHC_DATx should not exceed
1.5ns.
