1
Note this ball is always in MDIO mode.
2
This limit does not apply if no current can be drawn by external circuits on
IOVDDx, because then IOVDD follows to a suitable level.
3
This limit does not apply if no current can be drawn by external circuits on
AVDDx, because then AVDD follows to a suitable level.
Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.
All requirements applicable to each ball must be met. Where
multiple limits apply to a ball, each one must be met individually.
The limits apply according to the functionality of the balls at the
time. Balls that can be either analog or digital, that is, that have
two types indicated in the ball descriptions, must meet the
limits for both types. For ball types, see Table 10.
When powered up, it is required that all ground balls and
ADC_REFN be connected together to a node referred to as
GND in Table 9. The limits that are listed must be reduced by
any difference between any GNDs. Also, it is required that
AVDD3 is connected to AVDD4 and that IOVDD1 to IOVDD3
are connected together.
ESD CAUTION
