analysis to separate traces with significant parallelism or are otherwise "noisy". Use 6 mils trace
and separation. Clocks get extra separation and more precise balancing.

Supply Voltage Sequencing and Separation Cautions
(PLLVDD), and Core VDD (VDD).
Figure 2. Supply Voltage Sequencing and Separation Cautions
The relationship between SDVDD and OVDD is non-critical during power-up and power-down sequences.
Both SDVDD (2.5V or 3.3V) and OVDD are specified relative to VDD.
5.2.1.1
Power Up Sequence
If OVDD/SDVDD are powered up with VDD at 0 V, then the sense circuits in the I/O pads will cause all pad
output drivers connected to the OVDD/SDVDD to be in a high impedance state. There is no limit on how
long after OVDD/SDVDD powers up before VDD must powered up. VDD should not lead the OVDD,
SDVDD or PLLVDD 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
s to avoid turning
on the internal ESD protection clamp diodes.
The recommended power up sequence is as follows:
1. Use 1
s or slower rise time for all supplies.

Time
Notes:
VDD should not exceed OVDD, SDVDD or PLLVDD by more than
0.4 V at any time, including power-up.
Recommended that VDD/PLLVDD should track OVDD/SDVDD up to
0.9 V, then separate for completion of ramps.
Input voltage must not be greater than the supply voltage (OVDD, SDVDD,
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.
