Power-Up Sequence
PES24N3, the power-up sequence must be as follows:
are avoided. There are no maximum time limitations in ramping to valid power levels. The power-down sequence must be in the reverse order of the
power-up sequence.

Serial Link
This section describes the sequence in which various voltages must be applied to the part during power-up to ensure proper functionality. For the
1. V
2. V
3. V
When powering up, each voltage level must ramp and stabilize prior to applying the next voltage in the sequence to ensure internal latch-up issues
Typical power is measured under the following conditions: 25°C Ambient, 35% total link usage on all ports, typical voltages defined in Table 14.
Maximum power is measured under the following conditions: 70°C Ambient, 85% total link usage on all ports, maximum voltages defined in
All power measurements assume that the part is mounted on a 10 layer printed circuit board with 0 LFM airflow.
Values based on systems running at recommended supply voltages, as shown in Table 12.
