Note that the total capacitance of CMD and DAT lines will be consist of C
HOST
, C
BUS
and one C
CARD
only because they are
connected separately to the SD Memory Card host.
Host should consider total bus capacitance for each signal as the sum of C
Host should consider total bus capacitance for each signal as the sum of C
HOST
, C
BUS
, and C
CARD
, these parameters are
defined by per signal. The host can determine C
HOST
and C
BUS
so that total bus capacitance is less than the card estimated
capacitance load (C
L
=40 pF). The SD Memory Card guarantees its bus timing when total bus capacitance is less than
maximum value of C
L
(40 pF).
