5.4.1
PLL Power Filtering
To further enhance noise isolation, an external filter is strongly recommended for PLL analog VDD pins.
resistor and capacitors should be placed as close to the dedicated PLLVDD pin as possible.

5.4.2
Supply Voltage Sequencing and Separation Cautions
The relationship between SDVDD and EVDD is non-critical during power-up and power-down sequences.
SDVDD (2.5V or 3.3V) and EVDD are specified relative to IVDD.
5.4.2.1
Power Up Sequence
If EVDD/SDVDD are powered up with IVDD at 0 V, the sense circuits in the I/O pads cause all pad output
drivers connected to the EVDD/SDVDD to be in a high impedance state. There is no limit on how long after
EVDD/SDVDD powers up before IVDD must power up. IVDD should not lead the EVDD, 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 500 us to avoid turning on
the internal ESD protection clamp diodes.
5.4.2.2
Power Down Sequence
If IVDD/PLLVDD are powered down first, sense circuits in the I/O pads cause all output drivers to be in a
high impedance state. There is no limit on how long after IVDD and PLLVDD power down before EVDD
or SDVDD must power down. IVDD should not lag EVDD, SDVDD, or PLLVDD going low by more than
