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.
