5.2.1.1
Power Up Sequence
If OV
DD
are powered up with V
DD
at 0 V, then the sense circuits in the I/O pads will cause all pad output
drivers connected to the OV
DD
to be in a high impedance state. There is no limit on how long after OV
DD
powers up before V
DD
must powered up. V
DD
should not lead the OV
DD
or PLLV
DD
by more than 0.4 V
during power ramp-up, or there will be high current in the internal ESD protection diodes. The rise times
on the power supplies should be slower than 1
μ
s to avoid turning on the internal ESD protection clamp
diodes.
The recommended power up sequence is as follows:
1. Use 1
μ
s or slower rise time for all supplies.
2. V
DD
/PLLV
DD
and OV
DD
should track up to 0.9 V, then separate for the completion of ramps with
OV
DD
going to the higher external voltages. One way to accomplish this is to use a low drop-out
voltage regulator.

Notes:
1.
VDD should not exceed OVDD or PLLVDD by more than 0.4 V
at any time, including power-up.
Recommended that VDD/PLLVDD should track OVDD up to
0.9 V, then separate for completion of ramps.
Input voltage must not be greater than the supply voltage (OVDD,
VDD, or PLLVDD) by more than 0.5 V at any time, including during power-up.
Use 1 ms or slower rise time for all supplies.
