Power Sequencing
The device requires its power rails to be applied in a specific sequence in order to ensure proper device
operation. During the power ramp up, before the power supplies are stable and if the I/O voltages are
supplied before the core voltage, there may be a period of time that all input and output pins will actively
be driven and cause contention and excessive current. To avoid actively driving the I/O pins and to
eliminate excessive current draw, apply the core voltages (VDD and AVDD) before the I/O voltages and
assert PORESET before the power supplies fully ramp up. VDD and AVDD must reach 90% of their
nominal value before GVDD, LVDD, and OVDD reach 10% of their value, see the following figure. I/O
voltage supplies—GVDD, LVDD, and OVDD—do not have any ordering requirements with respect to one
another.
Figure 3. Power-Up Sequencing Example
Note that the SerDes power supply (L[1,2]_nVDD) should follow the same timing as the core supply
(VDD).
The device does not require the core supply voltage and I/O supply voltages to be powered down in any
particular order.
