Limits to the current and to the interface speed must be taken into consid-
eration when using the expansion interface. The maximum current limit is
dependent on the capabilities of the used regulator. Additional circuitry
can also add extra loading to signals, decreasing their maximum effective
speed.
Analog Devices does not support and is not responsible for the
effects of additional circuitry.
